Electronics Mosfet power amplifier schematics


Posted on Feb 6, 2014

This simple mosfet power audio amplifier circuit, with TL071C and 2 mosfet power amplifiers can deliver up to 45W on 8 ohm. This schematic is based on Siliconix application and is based on variations of voltage on the 2 resistors serial inserted on the voltage supplier of the operational amplifier driver. Amplifier efficiency is 70%, distortions a

t cut frequency were at most 0. 2% at 20Hz on 8ohm and 10W. With a equalizer of +- 30V the mosfet audio amplifier can deliver 45W on 8 ohm and 70w on 4 ohm. Remember that this audio amplifier is not protected on shortcircuits so everytime you switch on check to see if the speaker is connected.
