Re: Digital to Analog Converters

It depends on how much resolution you need, but the easiest way to do an 8-bit D/A is to use a PWM channel and an RC filter. Just be sure the time constant of the filter is much larger than the period of the PWM signal. You can do a search on the internet to find examples of a PWM/RC D/A.
