DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
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 its published
specifications.

DESCRIPTION
1
VREF
Reference Input.
2
+In
Non Inverting Input.
3
–In
Inverting Input.
4
GND
Ground.
5
CS/SHDN Chip Select when LOW, Shutdown Mode when HIGH.
6
DOUT
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
+VCC
Power Supply.

NOTE: (1) For detail drawing and dimension table, please see end of data sheet or Package Drawing File on Web. (2) Performance Grade information is marked
on the reel. (3) Models with a slash(/) are available only in Tape and reel in quantities indicated (e.g. /250 indicates 250 units per reel, /2K5 indicates 2500 devices
per reel). Ordering 2500 pieces of ”ADS7817E/2K5“ will get a single 2500-piece Tape and Reel.
