20w mosfet power amplifier


Posted on Feb 6, 2014

This audio power amplifier uses two complementary MOSFETs (IRF9520 and IRF520) to deliver up to 20W into 8 © speaker. A TL071 op amp is used as an input amplifier. The MOSFETs should be heatsinked with a heatsink of better than 50C/ W capability. THD is less than 0. 15% from 100Hz to 10KHz.
