Circuit Description

The circuit diagram of 6W amplifier using TA 7222AP is given here. This circuit uses integrated audio amplifier IC TA 7222AP as its central part. This is a famous and widely used amplifier IC developed by Toshiba. The unique features of this IC make it suitable for amplifier circuits. The features include short circuit protection, thermal protection, high ripple rejection, low distortion, muting function etc. A suitable heat sink should be provided for this IC to operate safely.

12V DC power supply is used for powering this circuit. The audio amplifier IC TA 7222AP can deliver a maximum output power of up to 5.8 Watts to a 4 ohm load if the supply voltage is 12V. This amplifier is well suited for car radio applications because it can operate in a range of voltage, i.e. from 8V to 12V. In order to get maximum desired performance for this circuit, provide separate ground for input and output.
