5W Stereo Audio Amplifier Project Based On BA5406

Description


5W Stereo Audio Amplifier project based on BA5406 IC which is Β 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 5WΓ—2 can be produced when VCC=12 V and RL=3Ω, and 2.8 WΓ—2 when VCC=9V and RL=3Ω. The BA5406, which uses a high allowable power dissipation package, has a simple heat-sink design.
