power audio stereo amplifier IC TDA7379
power audio stereo amplifier IC TDA7379

Compact stereo audio power amplifier circuit using integrated circuit TDA7379 for 2x 38 Watts. Uses simple DC power supply or transformer, being suitable for several applications where a good quality amplifier and low cost. Ideal for, games, PC, portable audio, automobile, motorcycle, home theather.
With a minimum of components it can assemble this project.

Simple design of easy assembly, already includes the circuit of the power supply, only need to connect the transformer and the speakers. With a compact pcb allows an audio amplifier with reasonable power even using simple power supply.
The power can be from 8 to 20 Volts DC or transformer from 6 to 15 VAC.
The power at the maximum setting will be up to 38 Watts at 4 Ohms and 20VDC. With Stand-by circuit, it allows smooth on and off the amplifier without crackling.
This IC is equipped with protection against short and high temperature.

The integrated TDA7375 and TDA7377 can be used on this board, provided that the voltage limits for each of these are observed, which can be observed in the Datasheet.
