Schematic Volt

Using the TA8256BH audio amplifier IC can be designed a very simple 3 channel audio power amplifier for audio applications that require a small power .
This IC provides an output power of 6 watts per channel (at VCC = 20 V, f = 1 kHz, THD = 10%, RL = 8 Ω).

TA8256BH audio amplifier project is suitable for power amplifier of TV and home Stereo.
Some important build in functions of these audio circuit project , based on the TA8256BH are : audio muting circuit , thermal shut down protection circuit, over voltage protection circuit .
TA8256BH power amplifier can operate over a wide range input voltage from 10 to 30 volts .

To supply the required voltage to the  amplifier circuit minimum of 7 Volt and a maximum of 24 volts . Incurred sizable ouput for amplifier ic 300 W maximum output.
