Analog Comparator Peripheral Driver, for nrf52
Partially based on sam4l implementation of an analog comparator.
The comparator (COMP) compares an input voltage (VIN+) against a second input voltage (VIN-). VIN+ can be derived from an analog input pin (AIN0-AIN7). VIN- can be derived from multiple sources depending on the operation mode of the comparator.
Main features of the comparator are:
- Input range from 0 V to VDD
- Single-ended mode
- Fully flexible hysteresis using a 64-level reference ladder
- Differential mode
- Configurable 50 mV hysteresis
- Reference inputs (VREF):
- VDD
- External reference from AIN0 to AIN7 (between 0 V and VDD)
- Internal references 1.2 V, 1.8 V and 2.4 V
- Three speed/power consumption modes: low-power, normal and high-speed
- Single-pin capacitive sensor support
- Event generation on output changes
