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+ (Pin 2): Analog Input. This input must be free of noise
with respect to GND.
IN(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.
VREF (Pin 5): Reference Input. The reference input denes
the span of the A/D converter and must be kept free of
noise with respect to GND.
DOUT (Pin 6): Digital Data Output. The A/D conversion
result is shifted out of this output.
CLK (Pin 7): Shift Clock. This clock synchronizes the se-
rial data transfer.
VCC(Pin8):PowerSupplyVoltage.Thispinprovidespower
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.
DIN (Pin 5): Digital Data Input. The multiplexer address is
shifted into this input.
DOUT (Pin 6): Digital Data Output. The A/D conversion
result is shifted out of this output.
CLK (Pin 7): Shift Clock. This clock synchronizes the se-
rial data transfer.
VCC (VREF) (Pin 8): Power Supply and Reference Volt-
age. This pin provides power and denes the span of the
A/D converter. It must be kept free of noise and ripple by
bypassing directly to the analog ground plane.
