TPA3116D2 DIY Audio Class-D Amplifier

Tpa3116D2 is a booming power-class class D this time, because the power amplifier using this IC is very powerful and very simple, because this power amplifier is class-d, so the output efficiency is also very high. And in this post, I will make a class-d power amplifier using the TPA3116D2 IC with a BTL system that has an output of up to 100W. You can view the TPA3116D2 schematic and PDF PCB Layout in this post: TPA3116D2 Power amplifier class-D schematic. Immediately we make the PCB:

First print PCB layout using A4 paper size, you can use HVS paper or transfer paper. Use a laserjet printer don't use an inkjet printer.

Then make water to transfer the pathway to the PCB from the mixture mosquito repellent lotion (Diethyltoluamide 15%) and enough water.

Pour the liquid into the PCB to taste. Do not be too much because it will make it difficult when rubbing paper, the paper will be soft and easily destroyed. Conversely, if it is less,  the path will be difficult to attach to the PCB.

Attach the print paper to the PCB.

Give the plastic over it, then rub it gently while pressed so that the path can attach to the PCB properly.

After the PCB image has been transferred, repair the path if something is damaged when removing the paper. Then etching the PCB using ferric chloride or vixal and vanish.

After etching, check the PCB path again whether there is a short or not. Use the Avometer and turn the switch to Ohm meter.

After checking the path all is normal, masking PCB using UV curable solder mask. By giving masking this PCB makes it easy for us to solder the SMD component and also the TPA3116D2 IC itself so that the solder tin or solder paste does not overflow everywhere.

TPA3116D2 Power amplifier class-D schematic

Hello on this occasion, I will share the circuit scheme and PCB class-d power amplifier using IC TPA3116D2/ TPA3116, Power Amplifier IC TPA3116D2 use is already no doubt his abilities, you can see the power amplifier TPA3116D2 KIT test video below, which is supplied with a voltage of 12V 15A:

In the video I used the TPA3116D2 stereo kit for driving Subwoofer speaker 8 Inch 4 Ohm 200W, kit TPA3116D2 stereo can produce 50W + 50W. And for the circuit scheme that I will share this is PBTL mode or mono output which can produce 100W power. Below for the schematic TPA3116D2 PBTL Mode.

A little explanation with PBTL mode is quoted from the TPA3116D2 datasheet

Mono Mode (PBTL)

The TPA31xxD2 family can be connected in MONO mode enabling up to 100W output power. This is done by:

• Connect INPL and INNL directly to Ground (without capacitors) this sets the device in Mono mode during

power up.

• Connect OUTPR and OUTNR together for the positive speaker terminal and OUTNL and OUTPL together for

the negative pin.

• Analog input signal is applied to INPR and INNR

For friends who want to create their own PCB, I provide images and PDF files to be printed using transfer paper to the paper size A4, the following PCB layout design image and PDF files is at the end of the posting that you can download.

PCBWay after-sale service review

When I need PCB prototype and PCB assembly service, the first manufacturer jumps to my mind is PCBWay. Because of their good PCB quality and excellent service, you can get a quick response for any questions.

Recently I am planning to participate in makerfaire that held in my city. I plan to show my Arduino project and offer small gifts to the audience who likes my project. I chose PCBWay ruler as a gift that found in PCBWay open source community, it seems very good.

After 7 days I received the PCBWay ruler, here is the picture:

This ruler looks beautiful, right? Good silkscreen, matt black solder mask, immersion gold, but did you find out anything wrong?

Yes, the series of holes, only the first three holes were immersion gold. I don't know why this problem happen as I noted that all the holes must immersion gold. This is the first time I met a production problem with PCBWay. Ok, I guess there is a first time for everything.

So what to do next? I found there is “Open Dispute” on this order:

They have online after-sale system, wow, it’s good. I upload the picture, submit the reason and wait for their reply.

I don’t know how PCBWay generally deals with after-sale issues. To be honest I am a little nervous because I heard usually Chinese companies offer poorly after-sales service. I don’t know whether PCBWay will deal with such a small problem. It will be a loss for them if they reproduce and ship to me.

.

A few hours later I received emails from their after-sales team:

It’s such a surprise! They took responsibility for their mistakes and reproduce the ruler in 24 hours. From here we can see that PCBWay has very high standards for themselves and care the feeling of clients.

Now I receive the new ruler.

It left a deep impression on me. I don’t think other companies’ after-sales service can compare with PCBWay’s. They are the “Amazon” in PCB prototype and assembly field.

10 Channel Equalizer using 4558 IC

In this post, I will share about the equalizer for audio power amplifiers, more precisely the 10 Channel equalizer circuit. I designed this equalizer circuit using the op-amp 4558 IC as a signal amplifier that is regulated by capacitors and resistors. And the component that I use is the SMD component, why do I use the SMD component? because it can reduce the PCB dimension and reduce the noise level because the PCB path that can be pressed is as close as possible. For this 10 channel equalizer circuit scheme you can see below:

This equalizer circuit requires a symmetrical power supply of at least 12V to 15Volt, and settings ranging from RV 1 starting from 30Hz, 64Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 20kHz.

For PCB layout I use a double layer using  60mm mono potentiometer. Following PCB Layout for 10 Channel Equalizer:

2.1 HiFi Preamplifier LM1036 + Subwoofer Filter 4558

Hello friends, I have not updated this blog since I'm still busy with my latest project I uploaded on my youtube account. And on this occasion, I will share a series of HiFi preamplifier, more precisely 2.1 channel preamplifier. Wherein a 2.1 HiFi preamplifier circuit which serves as a tone control for two pieces of satellite speakers (stereo speakers) and also to set a low signal (subwoofer) / Low pass filter. Here is a circuit of 2.1 preamplifiers:

In the above circuit scheme using IC LM1036 for its stereo tone control, why I use LM1036 IC? because, this IC is very good for a stereo tone control circuit which has 4 settings that are low, high, balance and volume. The sound issued using the IC LM1036 is very clean and clear. And the stereo tone control circuit using the LM1036 IC is very much in the market, and it costs about $ 15- $ 20 USD and is usually equipped with additional Op-Amp IC.

And this is where the excess of this 2.1 Preamplifier circuit, there is a circuit of stereo LM1036 and 4558 preamp and 4558 subwoofer filter that makes your subwoofer speakers more kicked once. In addition, this HiFi preamplifier 2.1 series also I have equipped with regulator power supply 15V 7815 and 7915 so do not have to bother making a power supply circuit from AC to DC voltage. You just give AC voltage of at least 12V - 24V. Interested to make this circuit?

I have prepared Gerber files and Bill of materials, download link you can see at the end of this post.

Input Balance Power Amplifier 4558 - SMD

Input Balance Power Amplifier is a circuit which will filter the original signal with a shadow signal so it will get a low noise input and a clear signal that will be forwarded to the power amplifier. There is a shadow signal or weakened signal from various interference on long cable input, so expect to use long cable at input either microphone cable or output cable mixer and other audio accessories.

This Input Balance circuit is suitable for installation on Yiroshi Amplifier, SOCL 504, or another power amplifier with no input balance.

This input balance circuit is highly recommended, and it is recommended to use long cable accessories. Do not underestimate the use of long cables, therefore long cable usage is often disrupted by wild signal either from radio frequency, wireless, or other signals. Besides being used for field audio, this input balance circuit can also be used for car audio that already uses a power amplifier, which can filter out wild signals into the car's power amplifier. Usually called audio storing, where the output power amplifier will issue noise that will be louder if RPM up. This input balance circuit can overcome these constraints.

Yiroshi Power Amplifier - SMD

This is my third project for Yiroshi Power Amplifier Circuit, the power amplifier circuit is very super quality, many have tested the power of this Yiroshi power amplifier. Power amplifier Yiroshi suitable for outdoor or indoor or used for the bass amplifier (subwoofer amplifier). Previously I have made this Yiroshi amp circuit in a stereo version of Yiroshi amplifier, which I have tested and worked well. 

But in this post, I make this Yiroshi power amplifier circuit by using some component of SMD (Surface Mount Device) in buffer circuit and its driver. Some components that I change to SMD eg 2N5401 transistors with mmbt5401, 2N5551 and mmbt5551 and some capacitors and resistors. And for transistor driver still use the same transistor as Yiroshi previous amplifier, as well as on the final part of the transistor which still uses 2SC5200 and 2SA1943. Here's the circuit scheme:

6 reasons PCBWay is the best PCB manufacturer

There is an increasing number of online PCB prototype companies in recent years, and the price is getting lower and lower, which is definitely good news for an electronic enthusiast. So which company offer the most cost-effective service?

Here I recommend the highly acclaimed PCB manufacturer- PCBWay

Their high-quality PCB and perfect service win wide reputation from all over word engineers. Here are 6 reasons why we recommend PCBWay.

1. PCB prototype as low as $5/10 pcs

The goal of PCBWay is "Better, Faster, Cheaper". In order to help more electronic enthusiasts build projects at a lower price, they are the first manufacturer to announce PCB prototype price will drop to $5/10pcs. The actual PCB prototype price is $ 0 after using the coupon for new registrants. What’s more, the stencil only needs $10. And the same price for different solder mask color. Generally speaking, the delivery time of PCBWay is only 2-3 days.

2. High-quality Raw Material of PCBWay 

Compared with other PCB manufacturers who use low-quality conductive adhesive materials, PCBWay always insists on quality first, using high-quality raw materials. For detailed reference to “Refuse conductive adhesive technology in PCB manufacture” 

Different raw materials can cause a huge gap in quality. Professional evaluation agencies ever detected PCB copper thickness and raw materials flame resistance that from PCBWay are better than other manufacturers.

3. You can track PCB production progress in PCBWay background

Are you curious about your PCB production statue after place order? Many companies don't support such services, but in the PCBWay background system, you can see the progress of the PCB production and track the express number after shipment.

4.      Share your PCB design in PCBWay community

PCBWay always support the development of open-source community and ever sponsored the 2017 Open Source Hardware Summit. In order to help electronic enthusiasts communicate with each other better, you can share your PCB design in PCBWay community and vote the most popular PCB design. If others like your design and place order, you can get 10% commission.

5.       Apply for PCBWay sponsorship for your non-profit project

Above all, if you need PCB prototype service, just try PCBWay.

PCBWay will continue to improve its production capacity and bring more surprises to us. 

1600W Power Amplifier + Speaker Protector

Power amplifier with high power output that is greatly needed by many audiophiles. Especially for field or concert, and in addition to the SPL car audio designation. Eg for controlling the use of extreme subwoofer speakers. So it takes a lot of power.

And the following is a power amplifier circuit that can generate output power up to 1600Watt at 4Ohm speaker load. In addition to having a large power, the power amplifier is already equipped with the protection of speakers. The function of the protection speakers is that the speakers are protected by DC voltage which can damage the speakers. It also can cut off the output current when the circuit occurs, so the power amplifier circuit remains safe.

Back to the discussion of this power amplifier. This power amplifier uses 4 final sets of 2SC3264 and 2SA1295 transistors. Where each transistor can flow current up to 18A and has power 200W.

To get a large power, the role of power supply amplifier is very important. Power supply for this amplifier at least 20A with max voltage 100V.
