Hi,
I'm trying to drive a galvanometer which needs a differential input. It's not well documented (galvo board), but I tried driving it with a differential input from a DRV134, which doesn't work properly. The output of the
I can't work out what's going on.
Instead I'm hoping to use an op amp to drive it by putting -10 to 10v on the +ve pin and tying the -ve pin to ground.
The only problem is that I can't find a working circuit anywhere that uses an op amp to convert 0-5v to -10-10v, could anyone help me with this please?
Thanks for your time.
