ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling and
installation procedures can cause damage.

Analog Input: Positive Input of the Differential Analog Input.
Analog Input: Negative Input of the Differential Analog Input.
Input: Power Supply Voltage, +5V.
+VDD
CLK
Digital Input: Device System Clock. The system clock is in the form of a CMOS-compatible clock. This is a Schmitt-Trigger input.
DOUT/DRDY
Digital Output: Serial Data Output/Data Ready. A logic LOW on this output indicates 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 possible to run SCLK at a higher frequency than CLK. The normal state of SCLK is LOW.
Holding SCLK HIGH will either initiate a modulator reset for synchronizing multiple converters or enter power-down mode. This
is a Schmitt-Trigger input.
