AD8801 PIN DESCRIPTIONS
Pin Name Description
1 VREFH Common DAC Reference Input
2 O1 DAC Output #1, Addr = 0002
3 O2 DAC Output #2, Addr = 0012
4 O3 DAC Output #3, Addr = 0102
5 O4 DAC Output #4, Addr = 0112
6 SHDN Reference input open circuit, active low, all
DAC outputs open circuit. DAC latch settings
maintained.
7 CS
Chip Select Input, active low. When CS returns
high, data in the serial input register is decoded
based on the address bits and loaded into the tar-
get DAC register.
8 GND Ground
9 CLK Serial Clock Input, Positive Edge Triggered
10 SDI Serial Data Input

16 VDD
DAC Output #5, Addr = 1002
DAC Output #6, Addr = 1012
DAC Output #7, Addr = 1102
DAC Output #8, Addr = 1112
Asynchronous preset to midscale output setting,
active low. Loads all DAC latches with 80H.
Positive power supply, specified for operation at
both +3 V and +5 V.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although these devices feature proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
WARNING!
