Are there any op-amps that are guaranteed to not have a sink at the output and only rely on the current consumption of the load to bring down the voltage when it needs to? Internally, an op-amp with a single push-only transistor at the output.
I'm asking as I have a semi-elaborate setup with virtual rails where the op-amps hang on to, wherein the output of the op-amps changes the float of this virtual rail. Hence, having a strong feedback mechanism. That and the op-amps always probing how to keep everything balanced, makes for a recipe for disaster. So I was hoping to find a few push-only op-amps to replace some to alleviate this oscillation problem.
