I need some programmable power supply rails, maybe -5 to +40 volts or so. We have some OPA552s in stock, a nice 60 volt power opamp. It's a decomp, and it will be driving a big capacitive load, so there is an oscillation hazard. One of my guys got the model from TI and kluged it into LT Spice. The symbol is ugly but it seems to work. We don't know how to make it look like a real opamp.
This looks fine, even without C1. Maybe I'll include C1 on the pcb layout just to have another knob to turn.
I'd like to use the OPA552 thermal cutoff as a secondary, slowish current limit, but I'd have to tune the pcb thermal resistance somehow to control that. Maybe a bunch of thermal-zero-ohm jumpers? Maybe a tweakable amount of gap-pad under the board, or above the amp? I suppose I could selectively drill out vias on the rev A board, but that's really ugly.
I want a thermal conductivity trimpot. Or DAC.
