DESCRIPTION

CS
Chip Select Input
A logic low on this input enables the LTC1292/LTC1297. Power shutdown is activated on the LTC1297 when
CS is brought high.
These inputs must be free of noise with respect to GND.
GND should be tied directly to an analog ground plane.
The reference input defines the span of the A/D converter and must be kept free of noise with respect to GND.
The A/D conversion result is shifted out of this output.
This clock synchronizes the serial data transfer.
This supply must be kept free of noise and ripple by bypassing directly to the analog ground plane.
