Connection Considerations
The Voltage Reference Module operates independently of the comparator module. The output of
the reference generator may be connected to the V
and the VROE bit (VRCON<6>) is set. Enabling the Voltage Reference output onto the V
with an input signal present will increase current consumption. Configuring the V
output with V
The V
drive capability, a buffer must be used in conjunction with the Voltage Reference output for exter-
nal connections to V

Note 1: R is the Voltage Reference Output Impedance and is dependent upon the
REF
pin can be used as a simple D/A output with limited drive capability. Due to the limited
