Easy as pie AR envelope generator.
Simple Op Amp Relaxation LFO
About as simple as an LFO gets, all analog, triangle and square out.
LED Driver for Vactrol with OpAmp
This simulation compares two different LED configurations being driven by an op amp. 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.
