Description

TEMP

Temperature Sensor Voltage Output.

REFBUFIN

AI/O

Reference Input Voltage. The reference output and the reference buffer input.

PDREF

This pin allows the choice of internal or external voltage references. When LOW, the on-chip reference

is turned on. When HIGH, the internal reference is switched off and an external reference must be

used.

PDBUF

This pin allows the choice of buffering an internal or external reference with the internal buffer. When

LOW, the buffer is selected. When HIGH, the buffer is switched off.
