I've been searching around for ages, and I'm tearing my hair out.
I'm trying to implement a MIDI-to-CV converter. The idea is to use the low-voltage PWM output of a chip to drive the gate of a MOSFET which will be controlling a larger, regulated voltage that will then be filtered to DC to create a control voltage.
I know 16-bit PWM must exist somewhere, but figuring this out is driving me nuts. For CV, I don't need that high of a frequency, but I do need as good of resolution as I can manage. So I thought I'd ask here: are there any microcontrollers on the market with a true 16-bit output compare for PWM? Every data sheet I've pored over so far has left me scratching my head.
If I have to, I suppose I could implement the whole thing on one of my FPGA boards, but that seems like overkill...
