Function

19

A0

Address Pin 0. Signal level must be ≤V

20

A1

Address Pin 1. Signal level must be ≤V

21

LDAC

Digital Input Load DAC Control. Signal level must be ≤V

22

MSB

Power-On Reset State. MSB = 0 corresponds to zero-scale reset; MSB = 1 corresponds to midscale reset. The

signal level must be ≤V

23

RS

Active low resets both input and DAC registers. Resets to zero-scale if MSB = 0 and resets to midscale if MSB = 1.

Signal level must be ≤V

29

VDD

Positive Power Supply Input. The specified range of operation is 2.7 V to 5.5 V.
