GND (Pin 4): Analog Ground. GND should be tied directly
to an analog ground plane.
CS/SHDN (Pin 5): Chip Select Input. A logic low on this
input enables the LTC1286. A logic high on this input
disables and powers down the LTC1286.

CLK (Pin 7): Shift Clock. This clock synchronizes the serial
data transfer and determines conversion speed.
