TDA1554 / 22W Stereo Amplifier


Posted on Feb 23, 2013

Very simple and useful circuit for amplify the stereo signals .The circuit dissipates roughly 28 watts of heat, so a good heatsink is necessary. The chip should run cool enough to touch with the proper heatsink installed .the circuit operates at 12 Volts at about 5 Amps at full volume.

Lower volumes use less current, and therefore produce less heat. R1 is also a 5% resistor.
