600 watt audio amplifier (LM4702)


Posted on Dec 15, 2012

The circuit is based around LM4702 manufactured by NATIONAL semiconductors MJ11029-MJ11028 by ON semiconductors It is a high fidelity audio power amplifier. Designed for demanding consumer and pro-audio applications. You can also use this circuit with AV receivers, Audiophile power amps, Pro Audio High voltage industrial applications etc Amplifier output power maybe scaled by changing the supply voltage and number of output devices. The circuit includes thermal shutdown circuitry that activates when the die temperature exceeds 150°c. CIRCUIT?s mute function, when activated, mutes the input drive signal and forces the amplifier output to a quiescent state.
