TDA2052 60 Watt Amplifier with Mute and St-By Functions

Description: 

TDA2052 is a AB class amplifier which operates with (+,-25V) supply and generates 60 Watt power (sound) output. Since it has very low distortion and it is a AB class amplifier, it can be used in HI-FI systems. TDA2052 has mute and st-by functions so it can be controlled by external digital circuits. Very high temperature  and output short circuit protections  are included. You should use a heatsink to dissipate the excess heat.

30W MosFet Audio Amplifier IRF530-IRF9530

Description: 

This project was a sort of challenge: designing an audio amplifier capable of delivering a decent output power with a minimum parts count, without sacrificing quality.

The Power Amplifier section employs only three transistors and a handful of resistors and capacitors in a shunt feedback configuration but can deliver more than 18W into 8 Ohm with <0.08% THD @ 1KHz at the onset of clipping (0.04% @ 1W - 1KHz and 0.02% @ 1W - 10KHz) and up to 30W into a 4 Ohm load.
