The CV
vides a selectable reference voltage. Although its pri-
mary purpose is to provide a reference for the analog
comparators, it also may be used independently of
them.

a power-down function to conserve power when the
reference is not being used. The module’s supply refer-

able for the comparators and typically available for pin
output.
The comparator voltage reference has the following
features:
• High and low range selection
• Sixteen output levels available for each range
• Internally connected to comparators to conserve
• Output can be connected to a pin
