CS (Pin 1): Chip Select Input. A logic low on this input
enables the LTC1196. A logic high on this input disables
the LTC1196.

GND (Pin 4): Analog Ground. GND should be tied directly
to an analog ground plane.
V

noise with respect to GND.
D
result is shifted out of this output.
CLK (Pin 7): Shift Clock. This clock synchronizes the serial
data transfer.
V
power to the A/D converter. It must be kept free of noise
and ripple by bypassing directly to the analog ground
plane.
