I am not an electrical engineer (rather a photonics engineer), so I am looking for some direction on how to attack an issue I have.
Basically, I need to drive a 150 Ω load with a computerized controller. The controller I have (a National Instruments I/O device) produces a series of voltage step functions over time, but it's not rated up to the current and power that I need at my load.
What do I need between the controller and the load to fully power the load, without damaging the controller? And of what flavor, like common emitter, voltage follower, etc.?
Note: Precise multiplication of the input signal is not necessary, as the controller can be easily calibrated to account for any incidental offsets. (In fact, Vin does not need to equal Vout.) And fast switching is also not necessary.
