12 Volt Audio Amplifier Used IC TDA7222AP
This is the circuit diagram of a 6W audio power amplifier using the IC TA7222AP. IC TDA7222AP is an excellent integrated audio amplifier which can deliver 5.8W to a 4 Ohms load at 12V supply voltage. The IC has very good features like, muting function, low distortion, high ripple rejection, short circuit protection, thermal shut down etc. This amplifier can be operated from 8 to 12V and this makes it ideal for car radio applications.
