PIN DESCRIPTIONS
PIN
NAME
PIN DESCRIPTION
1+VIN
Analog Input: Positive Input of the Differen-
tial Analog Input
2
–VIN
Analog Input: Negative Input of the Differ-
ential Analog Input
3+VDD
Input: Power-Supply Voltage, +5V
4
CLK
Digital Input: Device System Clock. The
system clock is in the form of a CMOS-
compatible clock. This is a Schmitt-Trigger
input.
5
DOUT/DRDY
Digital Output: Serial Data Output/Data
Ready. A logic LOW on this output indi-
cates that a new output word is available
from the ADS1252 data output register.
The serial data is clocked out of the serial
data output shift register using SCLK.
6
SCLK
Digital Input: Serial Clock. The serial clock
is in the form of a CMOS-compatible clock.
The serial clock operates independently
from the system clock, therefore, it is pos-
sible to run SCLK at a higher frequency
than CLK. The normal state of SCLK is
LOW. Holding SCLK HIGH will either ini-
tiate a modulator reset for synchronizing
multiple converters or enter power-down
mode. This is a Schmitt-Trigger input.

ELECTROSTATIC
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.
