REF
The Voltage Reference module is typically used in conjunction with the Comparator module. The
comparator module’s inputs do not require very large drive, and therefore the drive capability of
the Voltage Reference is limited.
The Voltage Reference is a 16-tap resistor ladder network that provides a selectable voltage ref-
erence. The resistor ladder is segmented to provide two ranges of V
power-down function to conserve power when the reference is not being used. The VRCON reg-
ister controls the operation of the reference as shown in
in
result in an increasing output).
