5W Stereo Audio Amplifier




Description


5W Stereo Audio Amplifier project based on BA5406 IC which is  suitable for application like stereo radio cassette player, stereo components systems etc.

The Heart of the project, BA5406 is a dual OTL monolithic power IC with two built-in, high output speaker amplifier circuits. High output of 5W×2 can be produced when VCC=12 V and RL=3Ω, and 2.8 W×2 when VCC=9V and RL=3Ω. The BA5406, which uses a high allowable power dissipation package, has a simple heat-sink design.
