13.0 Voltage Reference (VREF)

13.1 Voltage Reference Overview

The SLG46110 has a Voltage Reference Macrocell to provide references to the two analog comparators. This macrocell can

supply a user selection of fixed voltage references, /3 and /4 reference off of the VDD power supply to the device, and externally

supplied voltage references from pin 4. The macrocell also has the option to output reference voltages on pin 10. See table below

for the available selections for each analog comparator. Also see Figure 39 below, which shows the reference output structure.
