LTC1096/LTC1096L
CS/SHDN (Pin 1): Chip Select Input. A logic low on this
input enables the LTC1096/LTC1096L. A logic high on this
input disables the LTC1096/LTC1096L and disconnects
the power to the LTC1096/LTC1096L.

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 free of noise and
ripple by bypassing directly to the analog ground plane.
