The IC TDA2009 Stereo Hi-Fi Class AB Power Amplifier circuit design with the intention of looks parallel to the IC 8W +8 W stereo amplifier circuits of the earlier tape.But it pray adjust the IC amplifier in the same way as a figure TDA2009.inside the IC in support of circuit amplifiers, Hi-Fi rank AB. And output terse circuit protection sectors as well.But nearby will be present changed according to the properties of the IC. The TDA2009 IC is to qualify from the power supply 8-24 volts, the current most of 1-2 amp.An output voltage watt 10 watt 24 volt load 4 ohms, 0.351% distortion by a frequency 1 kHz, frequency response from 10 Hz-50 kHz by -3 dB to 36 dB of grow and the strength. input make signs by 100 mV.
While raising the power supply circuit and input into the audio input.The audio input gone channel and absolute channel. desire it perform the same.So I explained the values of the missing channel merely lone box.gesticulate through C1 meant for protection dc stimulating To interfere with IC.
at that time liveliness to the input signal to pin 5 of IC.The non inverting pin wish not reach to time signals. The output from pin 8. Through C8 and to prevent DC and raise the low frequency response the better,so therefore sent to the spokesman.The C10 and C11 act to filter the light to look after the smooth sound
