Reminds me of audio amps which used an op amp's supply pins for the upper and lower drive.
You can cascode them too. Build a class-B amp with zero crossover distortion.
That’s a pretty mainstream technique actually. It’s a lot easier to stabilize if the op amp has good supply rejection—lots don’t, especially on the negative side.
In the last dozen years or so, AD and TI have come out with a lot of great
36V op amps, but for several years before that, they were dropping lots of good old HV parts such as the LF357 and AD743 , and only introducing 5-V ones. Using the supply pins to drive a Class B output stage lets you use LV parts for higher-voltage applications.Cheers
