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 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 its
published specifications.

PIN DESCRIPTIONS
PIN NAME DESCRIPTION
1+V
CC
Power Supply, 2.7V to 5V
2 CH0 Analog Input Channel 0
3 CH1 Analog Input Channel 1
4 CH2 Analog Input Channel 2
5 CH3 Analog Input Channel 3
6 COM Common reference for analog inputs. This pin is typically connected to V
REF
.
7
SHDN
Shutdown. When LOW, the device enters a very low power shutdown mode.
8V
REF
Voltage Reference Input. See Electrical Characteristic Table for ranges.
9+V
CC
Power Supply, 2.7V to 5V
10 GND Ground
11 GND 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.
