lm12 audio amplifier circuit diagram

Posted on Feb 5, 2014

This LM12 audio amplifier circuit will provide a high output power on a 8 ohms or 4 ohms load impedance. The maximum output power delivered by this LM12 audio amplifier is around 60 watts on a 4 ohms load and 100 watts on a 4 ohms load on each channel. A preamplifier stage based on the LM381N dual preamplifier integrated circuit and a power ampl

ifier stage based on the LM12 high power operational amplifier. To obtain more audio power from this audio amplifier you can use it in the bridge mode configuration, but in that way you will obtain a mono power amplifier circuit. If you want to use it in bridge configuration or stereo configuration just design the pcb board in the stereo mode configuration and modify the jumpers in this way :
