CS (Pin 1): Chip Select Input. A logic low on this input
enables the LTC1292/LTC1297. Power shutdown is acti-
vated on the LTC1297 when CS is brought high.
+IN, –IN (Pin 2, 3): Analog Inputs. These inputs must be
free of noise with respect to GND.
GND (Pin 4): Analog Ground. GND should be tied directly
to an analog ground plane.
