CS/SHDN

Chip select when LOW, shutdown mode when HIGH.

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

6

second clock pulse after the falling edge of CS enables the serial output. After one null bit the data is valid for the next 16

edges.
