22 Watt power amplifier with TDA2040V

Posted on Nov 1, 2012

This circuit uses the TDA2040V which is a monolithic power amplifier IC intended for use as a high quality, class AB audio power amplifier. Typically it provides 22W output power into 4ohm with 0.5% distortion, from 32V supply. The device is designed to operate from a split power supply and no electrical isolation is needed between the mounting tab and its heatsink. It provides a high output current and has very low harmonic and crossover distortion.
