I did some research:
PWM usually have 10bit resolution(1024) levels. 20Khz x 1k=20Mhz. if you goto 12bit resolution, you need 80Mhz clock.
But for DAC, 16bits is readily available. But it is a external component. Any uController that has 12bits DAC?
I need to do location position, My encoder has 512lines-->2k using quadrature encoding. How do I choose the PWM or DAC resolution??
