ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from per-
formance degradation to complete device failure. Burr-
Brown Corporation recommends that all integrated circuits
be handled and stored using appropriate ESD protection
methods.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet
published specifications.

REF
Reference Input.
2 +In Non Inverting Input.
3 –In Inverting Input. Connect to ground or to remote ground sense point.
4 GND Ground.
5 CS/SHDN Chip Select when LOW, Shutdown Mode when HIGH.
6D
OUT
The serial output data word is comprised of 12 bits of data. In operation the data is valid on the falling edge of DCLOCK. The
second clock pulse after the falling edge of CS enables the serial output. After one null bit the data is valid for the next 12 edges.
7 DCLOCK Data Clock synchronizes the serial data transfer and determines conversion speed.
8+V
CC
Power Supply.
