NOTES
1 Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
2 Max current is bounded by the maximum current handling of the switches,
maximum power dissipation of the package, and maximum applied voltage
across any two of the A, B, and W Terminals at a given resistance. Please refer to
TPC 22 for detail.
3 Package Power Dissipation = (TJ Max–TA)/θJA.

Negative Power Supply, specified for opera-
tion from 0 V to –2.7 V.
Terminal B of RDAC#2.
Terminal A of RDAC#2.
Wiper, RDAC#2, addr = 12
Digital Ground.
Active Low Input. Terminal A open-circuit
and Terminal B shorted to Wiper. Shut-
down controls both RDACs #1 and #2.
Chip Select Input, Active Low. When CS
returns high, data in the serial input register
is decoded, based on the address bit, and
loaded into the corresponding RDAC register.
Serial Data Input. MSB is loaded first.
Serial Data Output. Open Drain transistor
requires pull-up resistor.
Serial Clock Input. Positive Edge Triggered.
Positive Power Supply. Specified for opera-
tion at 2.7 V to 5.5 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
the AD5207 features 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.
