30.2 Overview

The analog comparator (AC) compares the voltage levels on two inputs and gives a digital output based on this comparison. The AC can be configured to generate interrupt requests and/or events based on several different combinations of input change.

The input selection includes analog port pins and internally generated inputs. The AC digital output goes through controller logic, enabling customization of the signal for use internally with the Event System or externally on the pin.

The dynamic behavior of the AC can be adjusted by a hysteresis feature. The hysteresis can be customized to optimize the operation for each application.

The individual comparators can be used independently (Normal mode) or paired to form a window comparison (Window mode).
