Analog Comparator
Functional Description
The analog comparator is an analog general purpose comparator that can be used as analog wakeup, or for any other measurement that can be performed by means of a coarse comparator. The comparator inputs can be routed to any of the GPIO pins. Reference voltage can be selected from WEDAC voltage (the same that is used in SDAC) or PMU reference. The comparator has three modes: low-power, normal, and high-speed. Each mode provides different power consumption and delay trade-offs. The comparator employs a configurable hysteresis window for noisy input signals. It can also operate without any active hysteresis configuration.
