I am trying to power a metal oxide sensor using the on-board DAC because I need to switch between multiple voltages (2-3.3V). However, I need around 150 mA while the on-board DAC provides something on the order of 10 mA. What is the easiest way to amplify the current using an op-amp or other transistor setup? I’ve tried modeling in circuitlab, but I’m not sure on how to properly include specific op-amps.
I’m not sure if this would fit your needs, but a simple opamp voltage follower is as easy as it gets
