LED Driver for Vactrol with OpAmp
https://analogoutputblog.wordpress.com/2022/05/04/how-to-vactrol/
This simulation compares two different LED configurations being driven by an op amp. Simulation Simulation
BiPolar +/- 10V to 0-5V
3.3V -> 5V Opamp scaling
Useful for microcontroller projects that only output 3.3v, but maybe we want something like 0-5V or 0-10V for CV.
