I have a DAC connected to a microcontroller with a precise signal. I am using it to power an induction load which is basically like a galvanometer. I don't know yet what the current is needed to drive this load but obviously an op amp will not do. I still need a clean linear response so is there any high output current op amp or other circuit to power the load. I'm guessing the load would be somewhere around 500mA but I don't have the tools in front of me. Even a simple schematic would be great. Thanks!
