Power audio amplifier schematics with Tda2005

Posted on Feb 6, 2014

The Tda2005 IC has a high output power: PO=10W+10W @ RL=2ohm, d=10% (stereo) and PO=20W @ RL=4ohm, d=1% (bridge) for Vs=14. 4V. The high reliability of the IC comes from the various protections against: output DC and AC short circuit to ground, overrating chip temperature, load dump voltage surge, fortuitous open ground and very inductive loads.

e IC can be used used in bridge (TDA2005M) or stereo (TDA2005S) amplifiers - with or without boostrap - with easily programmable gain and bandwidth. The Tda2005 needs a very low number of external components, and has a very simple mounting system with no electrical isolation between the package and heatsink.
