So far in this course we have looked at the SAM D20’s wide range of digital peripheral blocks; now it is the turn of the analog circuitry. It will come as no surprise to readers with experience from the world of 8-bit microcontrollers that we will be looking in detail at both the analog-to-digital converter (ADC) and analog comparator (AC); and to those we also add the digital-to-analog converter (DAC).
