These parameters are characterized but not tested.

† Data in “Typ” column is at 5.0V, 25°C unless otherwise stated. These parameters are for design guidance

only and are not tested.

Note 1:

ADRESH and ADRESL registers may be read on the following TCY cycle.

See Section 12.4 “A/D Acquisition Requirements” for minimum conditions.

Full range for PIC12HV752 powered by the shunt regulator is the 5V regulated voltage.
