6DOUT

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.

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.
