V
OUT
(Pin 1): The DAC Output. The output will swing from
REFLO to REFHI in unipolar mode and from (2 • REFLO
– REFHI) to REFHI in bipolar mode.
V
RST
(Pin 2): The user-defined voltage to which the output
gets reset when CLR is active, when any of the supplies
drop below 2.5V or when the part powers-up. The output
will stay at this voltage until a new code is loaded into the
DAC register.
DV
DD
(Pin 3): The Digital Positive Supply Input. 4.75V ≤
DV
DD
≤ 5.25V.
DGND (Pin 4): Digital Ground.
D
IN
(Pin 5): The TTL Level Input for the Serial Interface
Data. Data on the D
IN
pin is latched into the shift register
on the rising edge of the serial clock. Data is loaded as one
16-bit word, MSB first.
D
OUT
(Pin 6): The output of the shift register that be-
comes valid on the rising edge of the serial clock.
CLK (Pin 7): The TTL Level Input for the Serial Interface
Clock.
