I am working on a project where I would like to level shift a PWM signal, from a microcontroller I have ether a 5v or 3.3v (not super stable voltage) 1kHz PWM signal, this I would like to shift to a voltage from a stable and precise reference (2.048v, 2.5v or other) then it goes through a R/C Filter so I get a smooth stable analog output.
The part I cant figure out is how to level shift a PWM signal so it can be used in an R/C Filter
