Pin No.

Description

39

REF−

AI

Reference Input Negative Terminal. REF− can span from AVSS to AVDD − 1 V. Reference can be selected

through the REF_SELx bits in the setup configuration registers.

40

REF+

AI

Reference Input Positive Terminal. An external reference can be applied between REF+ and REF−. REF+

can span from AVDD to AVSS + 1 V. Reference can be selected through the REF_SELx bits in the setup

configuration registers.

EP

P

Exposed Pad. Solder the exposed pad to a similar pad on the PCB under the exposed pad to confer

mechanical strength to the package and for heat dissipation. The exposed pad must be connected to

AVSS through this pad on the PCB.
