High-End Power Amplifier LME49810 2SC5200 2SA1943

High Power Amplifier LME49810 2SC5200 2SA1943

High-End Power Amplifier Circuit using ic LME49810 as a driver amplifier and using Transistor 2SC5200 2SA1943. LME49810 is a high fidelity audio power amplifier buffer driver. 

High-End Power Amplifier output power may be scaled by changing the power supply voltage and number of final stage transistors (Transistor Booster) . The LME49810 minimum output current is 50mA. When using a discrete output stage the LME49810 is capable of delivering in excess of 300 watts into a single-ended 8Ω load. 

Unique to the LME49810 is an internal Baker Clamp. This clamp insures that the amplifier output does not saturate when over driven. The resultant “soft clipping” of high level audio signals suppresses undesirable audio artifacts generated when conventional solid state amplifiers are driven hard into clipping. The LME49810 includes thermal shutdown circuitry that activates when the die temperature exceeds 150°C. The LME49810's has mute function, when activated, mutes the input drive signal and forces the amplifier output to a quiescent state.

A bit out of the discussion of electronics, but still on the basis of electronics that how to apply the LED circuit  in acrylic field. This is a Simple project on making LED acrylic sign. So I will share tips how to make it step by step. What is required and how to make use in LED acrylic sign.

First, this part and tools you need to making LED Acrylic Sign:
part and tool LED Acrylic Sign

Parts : 
  • Acrylic on image using Acrylic 10cm x 20cm 
  • Some Cable to connect LED with Power Supply or Battery
  • LED Strip's or you can assembled LED circuit, i will describe below.
Tools :
  • Pencil to draw sign on Acrylic Field
  • Sandpaper to sandpapering acrylic sign
  • Ruller to scratch that sign exactly at the right position
  • Cutting Plier to cut the cabel
  • Cutter to cut the wrapping layer of acrylic on the sign
  • Solder and Solder tin to soldering cable with LED Strip's or Assembled LED Circuit

If the parts and tools are ready , let's create a this LED Acrylic Sign simple project and so manual !
Take acrylic and drawing sign in reverse, in the picture below I write in reverse. This function to mark the acrylic wrapper to be exfoliated. in the next step.

And if the acrylic is reversed, that text "" is clearly visible
Make Acrylic Sign

Then rub using sandpaper, on the part of the sign. This function to refract light LED, so that the LED illumination only on the sign.

Car power amplifier circuit using C5100 / A1908

Car amplifier is not very common as a project, because it is usually difficult to build, and expensive. A small error during assembly will result in power amps are not functioning properly. I suggest that you use the PCB for this amplifier. Even so, this circuit is simple to build, compact, relatively inexpensive, and provide a level of performance that will satisfy most of the needs of your car audio.

Simple 10W High Power LED Driver Circuit

This is my project for handmade flashlight when using 10W High Power LED voltage 12V DC. Indeed, by using this LED light produced is very bright. However, to use this LED requires a power of 10W and 12V stabilized voltage, so that LEDs are more durable long lasting without reducing the productivity of the light produced High Power LED's.

So it takes a LED driver circuit, precisely to control the voltage current and voltage itself. Here ne driver circuit is simple and easy to manufacture only need a few components that are easy to find in stores store and the price is very affordable. It also can use recycled components from the junk PSU.

Power Amplifier Circuit for Audio PC

Frequently, the audio field from a PC (Personal Computer) fabricated-in speakers is flat. A capacity intensifier is needed to get an elevated volume. Here is an effortless circuit to intensify the PC's sound yield. 
PC Power Amplifier
The circuit is constructed around capacity enhancer IC LA 4440 (IC1) and a few alternate parts. LA4440 is a double channel sound capacity speaker. It has level twisting over a vast run of flat to towering frequencies with exceptional channel detachment. Inbuilt double channels prepare it for stereo and extension speaker provisions.

This based power amplifier circuit using LA4440 IC

In double mode LA4440 gives 6 watts for every divert and in scaffold mode 19-watt yield. It has swell denial of 46 dB. The sound impact might be grasped by utilizing several 6-watt speakers. Associate binds 2, 6 and ground of IC1 to the stereo jack which is to be utilized with the PC. Collect the circuit on a customary-reason PCB and encase in a suitable bureau. The circuit works off managed 12V capacity supply. It is suggested to utilize sound enter socket in the circuit plank. Utilize a decent hotness-sink for LA4440.
