ELECTROSTATIC

DISCHARGE SENSITIVITY

Electrostatic discharge can cause damage ranging from per-

formance degradation to complete device failure. Texas

Instruments 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.

NAME

DESCRIPTION

Reference Input.

+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.

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.

Power Supply.

NOTES: (1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI website at

www.ti.com.

(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 ”ADS7822E/2K5“ will get a single 2500-piece tape and reel.
