Hi,
I am doing a project of a programmable DC power supply, the programmable resolution is 1mV/1mA, PWM DAC is a low cost solution, but I am a litter worrying about the PWM DAC resolution, many microcontrollers have a 16-bits PWM integrated, but I am a little worry about the real performance like settling time, ripple noise, transient response. is there any expert can give some suggestion?
