I am building an amplifier with multiple op-amps, and it seems that some are overheating. Here is the schematic:
U62 heats up the most (too hot to touch), U63 also heats up but a little less, U64 heats up the least but still significantly. U65/66 don't heat up at all. DAC0_OUT1/2 are current outputs from a DAC with a maximum output of 20mA. The amplifiers that are heating up are all LM7372, powered with a split supply of +/-15V. (From a 7815 and 7915). I've confirmed the voltages on the supply pins and they are correct. I'm not even sure where to begin debugging this. Strangely enough, the circuit actually functions - I see the expected voltages at the outputs of the amps that heat up. However, the amp should only be consuming a few mA, so no reason it should be heating up - any ideas?
If I've left out any information that could be helpful let me know! Thanks!
