STK4241V - 120 Watt Stereo Amplifier Circuit

Here is a 120 watt stereo amplifier circuit using STK4241V. The MAX9710 a stereo audio power amplifier IC capable of delivering 2 x 120 Watts of out put to 8 Ohm loads. MAX9710 can be operated from a single ±32V to ±54V power supply.

This amplifier circuit is suitable for home power audio devices. The STK4241V amplifier specifications might lead you to believe that it can use supply voltages of up to ±78V. With zero input signal (and therefore no output) it might, but I don't recommend anything greater than ±45V if 8 ohm loads are expected, although ±54V will be fine if you can provide good heatsinking.
