Analog Input Channel 5.
Analog Input Channel 6.
Analog Input Channel 7.
Ground reference for analog inputs. Sets zero code
voltage in single ended mode. Connect this pin to ground
or ground reference point.
Shutdown. When LOW, the device enters a very low
power shutdown mode.
Voltage Reference Input. See Specification Table for
ranges.
Power Supply, 2.7V to 5V.

Serial Data Output. Data is shifted on the falling edge of
D
CLK
. This output is high impedance when
CS is high.
Busy Output. Busy goes low when the DIN control bits
are being read and also when the device is converting.
The Output is high impedance when CS is High.
Serial Data Input. If CS is LOW, data is latched on rising
edge of D
CLK
.
Chip Select Input. Active LOW. Data will not be clocked
into D
unless CS is low. When CS is high D
OUT
is high
impedance.
External Clock Input. The clock speed determines the
conversion rate by the equation f
CLK
= 24 f

NOTES: (1) Models with a slash (/) are available only in Tape and Reel in the quantities indicated (e.g., /2K5 indicates 2500 devices per reel). Ordering 2500 pieces
of “ADS8344E/2K5” will get a single 2500-piece Tape and Reel.

conditions for extended periods may affect device reliability.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
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 specifi-
cations.
