• IC1_______________TDA2009A

3. The TDA 2009A
• 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.
• 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.

8. The input connection
• 1 – tip : audio out left channel;
• 2 – 1° ring : audio out right channel;
• 3 – 2° ring : microphone line in;
• 4 – 3° ring/sleeve : ground – common for microphone and audio out.
