NOTE: (1) Stresses above those listed under “Absolute Maximum Ratings”
may cause permanent damage to the device. Exposure to absolute maximum
conditions for extended periods may affect device reliability.
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.

COM
Ground Reference for Analog Inputs. Sets zero code voltage in single-ended mode. Connect this pin to ground or ground reference
point.
7
SHDN
Shutdown. When LOW, the device enters a very low power shutdown mode.
8
V_REF
Voltage Reference Input. See Electrical Characteristics Table for ranges.
9
+V_CC
Power Supply, 2.7V to 5V
10
GND
Ground. Connect to Analog Ground
11
GND
Ground. Connect to Analog Ground.
12
DOUT
Serial Data Output. Data is shifted on the falling edge of DCLK. This output is high impedance when CS is HIGH.
13
BUSY
Busy Output. This output is high impedance when CS is HIGH.
14
DIN
Serial Data Input. If CS is LOW, data is latched on rising edge of DCLK.
15
CS
Chip Select Input. Controls conversion timing and enables the serial input/output register.
16
DCLK
External Clock Input. This clock runs the SAR conversion process and synchronizes serial data I/O. Maximum input clock frequency
equals 2.4MHz to achieve 100kHz sampling rate.
