FUNCTION
NAME
Power-Down Lockout (Digital Input)
1: Normal operation.
0: Disallows shutdown (device cannot be powered down).
PDL

Reset Value Input (Digital Input)
1: Tie to V
DD
to select midscale as the output reset value.
0: Tie to DGND to select 0V as the output reset value.
RSTVAL

Active-Low Chip-Select Input (Digital Input)
Serial Data Input. Data is clocked in on the rising edge of SCLK.

Reset DAC Input (Digital Input). Clears the DAC to its predetermined (RSTVAL) output state. Clearing the
DAC will cause it to exit a software shutdown state.

11
Power-Down Input (Digital Input). Pulling PD high when
PDL
= V
DD
places the IC into shutdown with a
maximum shutdown current of 20μA.
PD
12
Buffered Reference Output/Input. In internal reference mode, the reference buffer provides a +2.5V
(MAX5120) or +1.25V (MAX5121) nominal output, externally adjustable at REFADJ . In external reference
mode, disable the internal reference by pulling REFADJ to V
DD
and applying the external reference to REF.
REF
14
Positive Power Supply. Bypass with a 0.1μF capacitor in parallel with a 4.7μF capacitor to AGND.

16
Analog Reference Adjust Input. Bypass with a 33nF capacitor to AGND. Connect to V
DD
when using an
external reference.
