6.5 COMP — Comparator

The comparator (COMP) compares an input voltage (VIN+) against a second input voltage (VIN-). VIN+

can be derived either from an analog input pin (AIN0-AIN6) or VDD/2. 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 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

• Event generation on output changes

• UP event on VIN- > VIN+

• DOWN event on VIN- < VIN+

• CROSS event on VIN+ and VIN- crossing

• READY event on core and internal reference (if used) ready
