A car stereo amplifier using TDA2040
circuit shown here. TDA2040 is a monolithic integrated audio amplifier
operating in Class AB mode. The IC has built in short circuit
protection circuits and thermal very close and more about it can be
operated from a single source. The amplifier can deliver 12 watts into a
8 ohm speaker.

In the circuit of the IC is connected to
operate from the 12V line cars. Capacitor C7 is a DC-decoupling
capacitor and R4 provides. Network consisting of resistor R5 and
capacitor C5 provides high frequency stability and avoids any
possibility of oscillation. C6 capacitor couples the output circuits to
the speaker. C2 and C1 are the filters of the power supply.
