PIN FUNCTIONS
LTC1196
CS (Pin 1): Chip Select Input. A logic low on this input
enables the LTC1196. A logic high on this input disables
the LTC1196.
IN
with respect to GND.
IN
with respect to GND.
GND (Pin 4): Analog Ground. GND should be tied directly
to an analog ground plane.
V
the span of the A/D converter and must be kept free of
noise with respect to GND.
D
result is shifted out of this output.
CLK (Pin 7): Shift Clock. This clock synchronizes the se-
rial data transfer.
V
to the A/D converter. It must be kept free of noise and ripple
by bypassing directly to the analog ground plane.

LTC1198
CS/SHUTDOWN (Pin 1): Chip Select Input. A logic low
on this input enables the LTC1198. A logic high on this
input disables the LTC1198 and disconnects the power
to THE LTC1198.
CHO (Pin 2): Analog Input. This input must be free of
noise with respect to GND.
CH1 (Pin 3): Analog Input. This input must be free of noise
with respect to GND.
GND (Pin 4): Analog Ground. GND should be tied directly
to an analog ground plane.
