The ADC converts analog voltages to digital values. The ADC has 12-bit resolution and is capa-
ble of converting up to 200K samples per second. The input selection is flexible, and both single-
ended and differential measurements can be done. For differential measurements an optional
gain stage is available to increase the dynamic range. In addition several internal signal inputs
are available. The ADC can provide both signed and unsigned results.
ADC measurements can either be started by application software or an incoming event from
another peripheral in the device. The latter ensure the ADC measurements can be started with
predictable timing, and without software intervention. The ADC has one channel, meaning there
is one input selection (MUX selection) and one result register available.
Both internal and external analog reference voltages can be used. A very accurate internal
1.00V reference is available.
An integrated temperature sensor is available and the output from this can be measured with the
ADC. A VCC/10 signal and the Bandgap voltage can also be measured by the ADC.
