Mosfet Audio Amplifier 20W
This audio power amplifier makes use of two complementary MOSFETs (IRF9520 and IRF520) to supply up to 20W into eight O speaker. A TL071 op amp is utilized as an input amplifier. The MOSFETs should certainly be heatsinked having a heatsink of far better than 50C/W capability. THD is less than 0.15% from 100Hz to 10KHz.
