Inverting input. Connect to ground or remote
sense point.

Ground
5
Chip select when low; shut-down mode when
high.
6
Serial output data word comprises 12 bits of
data. In operation, data is valid on falling
edge of DCLOCK. Second clock pulse after
falling edge of CS/SHDN enables serial
output. After one null bit, data is valid for
next 12 edges.
7
Data clock synchronizes serial data transfer.
