The serial output data word is comprised of 16
bits of data. In operation the data is valid on the
falling edge of DCLOCK. The second clock
pulse after the falling edge of CS enables the
serial output. After one null bit, data is valid for
the next 16 edges.
7 DCLOCK Data Clock synchronizes the serial data transfer
and determines conversion speed.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instruments
recommends that all integrated circuits be handled with appropriate
precautions. Failure to observe proper handling and installation proce-
dures 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.
