Another project from Rajkumar Sharma of Electronics Lab a 5W Stereo Audio amplifier based on BA5406:
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.
These look more like ads than “project logs”…
I get what you are saying, but the link has schematics, parts list and board graphics. I didn’t see anywhere to purchase the item – to me that is not an ad.
Eh, fair enough. :-)
