Additional descriptions of the device pins follows.
TABLE 3-1:
3.1
Positive analog input. This input can vary from IN- to
V
3.2
Negative analog input. This input can vary ±100 mV
from V
3.3
The CS/SHDN pin is used to initiate communication
with the device when pulled low and will end a
conversion and put the device in low power standby
when pulled high. The CS/SHDN pin must be pulled
high between conversions.

The SPI clock pin is used to initiate a conversion and to
clock out each bit of the conversion as it takes place.
See Section 6.2 “Maintaining Minimum Clock
Speed” for constraints on clock speed.
3.5
The SPI serial data output pin is used to shift out the
results of the A/D conversion. Data will always change
on the falling edge of each clock as the conversion
takes place.
