So I have a setup that will output varying voltages between 0-5V. Im looking for the best method to convert this waveform up to ~100V. Any suggestions?
I would also like to note that there will eventually be two analog pins that will be outputting different voltages that will need to be in sync to one another after its boosted up to 100V. Im ok with a buffer time in between as long as I can sync the buffer times so that the outputs are synced
Sure, it depends on how linear you need it, and how much electronics you know.
You could even put a couple of booster transistors on the output of a regular op-amp, usually this is done for current, but it should work for voltage, too.
Note that you'll need a power supply of at least 100V to power your amplifier.
Is there a more cost effective option maybe with discrete parts?
It's usually cheaper (and easier) to use an integrated circuit. And, if you start building higher voltage circuits with discrete components there is a higher chance of frying parts (which obviously adds to the cost).
