![]() ![]() With the help of PRS and DMA, the ADC can operate without CPU intervention, minimizing current consumption or allow the core to do other work. ![]() The integrated input mux can select ADC-input from 8 external pins or 6 internal signals. The maximum resolution is 12 bits, and one million samples per second can be achieved at this resolution.
