5.16 10-Bit SAR ADC
The device includes a 10-bit SAR ADC using a switched capacitor architecture which converts an analog
input signal to a digital value at a maximum rate of 62.5-k samples per second (ksps) for use by the DSP.
This SAR module supports six channels that are connected to four general purpose analog pins (GPAIN
[3:0]) which can be used as general purpose outputs.
The device SAR supports the following features:
