LTC1091/LTC1092
CS (Pin 1): Chip Select Input. A logic low on this input
enables the LTC1091/LTC1092.
CH0, CH1/+ IN, – IN (Pins 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.
DIN (Pin 5)(LTC1091): Digital Data Input. The multiplexer
address is shifted into this input.
VREF (Pin 5)(LTC1092): Reference Input. The reference
input defines the span of the A/D converter and must be
kept free of noise with respect to AGND.
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 serial
data transfer.
VCC(VREF)(Pin 8)(LTC1091): Positive Supply and Refer-
ence Voltage. This pin provides power and defines the
span of the A/D converter. It must be kept free of noise and
ripple by bypassing directly to the analog ground plane.
VCC (Pin 8 )(LTC1092): Positive Supply Voltage. This pin
provides power to the A/D converter. It must be kept free
of noise and ripple by bypassing directly to the analog
ground plane.
LTC1093/LTC1094
CH0 to CH5/CH0 to CH7 (Pins 1 to 6/Pins 1 to 8): Analog
Inputs. The analog inputs must be free of noise with
respect to AGND.
COM (Pin 7/Pin 9): Common. The common pin defines the
zero reference point for all single-ended inputs. It must be
free of noise and is usually tied to the analog ground plane.
DGND (Pin 8/Pin 10): Digital Ground. This is the ground
for the internal logic. Tie to the ground plane.
V – (Pin 9/Pin 11): Negative Supply. Tie V – to most
negative potential in the circuit. (Ground in single supply
applications.)
AGND (Pin 10/Pin 12): Analog Ground. AGND should be
tied directly to the analog ground plane.
