Hi there - on a board I am redesigning I need a transimpedance amplifier that takes a 0-2ma input and outputs -10 to 10V. I don't care if -10 corresponds with 0ma or 2ma, but I do of course need linearity. The 0-2ma signal is being generated by a DAC onboard a Silicon Labs C8051F360
So - is there any way to accomplish this with a single op-amp? I have a quad op-amp on board that I'm using 3/4 of the op-amps on already, so it'd be really nice if I didn't have to throw another chip on there, but I'll survive either way. To do it with two op-amps I could simply run the current through a transimpedance amp with the non- inverting terminal grounded, and then do a summing amp with some voltage reference to get it into the right range. But I'd really prefer to stick with just one op-amp.
Thanks!
