The IC 10W +10 W stereo amplifier circuit design that looks similar to the IC 8W +8 W stereo amplifier circuits of the previous album.But it will change the IC amplifier as a number TDA2009. Within the IC for circuit amplifiers, Hi-Fi class AB.And output short circuit protection sectors as well.But there will be different according to the properties of the IC.
The Special feature
The TDA2009 IC is to qualify from the power supply 8-24 volts, the current maximum of 1-2 amp.An output voltage watt 10 watt 24 volt load 4 ohms, 0.351% distortion at a frequency 1 kHz, frequency response from 10 Hz-50 kHz at -3 dB to 36 dB of gain and the strength. input signal at 100 mV.
When raising the power supply circuit and input into the audio input.The audio input left channel and right channel. Will it work the same.So I explained the principles of the left channel only one box. The signal through C1 for protection dc electric To interfere with IC.
Then go to the input signal to pin 5 of IC.The non inverting pin will not extend to phase signals. The output from pin 8. Through C8 and to prevent DC and increase the low frequency response the better,then sent to the speaker.The C10 and C11 serve to filter the light to protect the smooth sound … Tub..Tub… at the time of launch noise.
This is PCB layout of this circuit, notice: C-220uf = C-470uF
We was adapted increase powerful sound.
Power Amplifier BCL 18W by IC TDA2009
TDA2009 Ampl BCL (bridge amplifier) 18W ,Supply volt = 23V 2A
The TDA2009 be 10 +10W STEREO AMPLIFIER integrated circuits interesting again the one number. We try to bring do the circuit amplifies 18W sizes better or Power Amplifier BCL 18W by IC TDA2009. Be circuit character model 18W Bridge amplifier the sound better model OTL amp. By use power supply just one group be 23V only. Make good convenient. When use 4 ohm loudspeakers. Will give the electric power about 18watt or 20Watt. If you want to the system stereo as a result just build enhance again the circuit. Request have fun 18W Bridge amplifier TDA2009 please sir.
