VREF (Pin 1): Reference Input. The reference input defines
the span of the A/D converter and must be kept free of
noise with respect to GND.
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.
CONV (Pin 5): Convert Input. A logic high on this input
starts the A/D conversion process. If the CONV input is left
high after the A/D conversion is finished, the part powers
down. A logic low on this input enables the SDO pin,
allowing the data to be shifted out.
SDO (Pin 6): Digital Data Output. The A/D conversion
result is shifted out of this pin.
SCK (Pin 7): Shift Clock Input. This clock synchronizes the
serial data transfer.
VCC (Pin 8): Positive Supply. This supply must be kept
free of noise and ripple by bypassing directly to the
analog ground plane.

LTC1865 (MSOP Package)
CONV (Pin 1): Convert Input. A logic high on this input
starts the A/D conversion process. If the CONV input is left
high after the A/D conversion is finished, the part powers
down. A logic low on this input enables the SDO pin,
allowing the data to be shifted out.
CH0, CH1 (Pins 2, 3): Analog Inputs. These inputs must
be free of noise with respect to AGND.
AGND (Pin 4): Analog Ground. AGND should be tied
directly to an analog ground plane.
DGND (Pin 5): Digital Ground. DGND should be tied
directly to an analog ground plane.
SDI (Pin 6): Digital Data Input. The A/D configuration
word is shifted into this input.
CONV (Pin 1): Convert Input. A logic high on this input
starts the A/D conversion process. If the CONV input is left
high after the A/D conversion is finished, the part powers
down. A logic low on this input enables the SDO pin,
allowing the data to be shifted out.
CH0, CH1 (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.
LTC1865 (SO-8 Package)
SDO (Pin 7): Digital Data Output. The A/D conversion
result is shifted out of this output.
SCK (Pin 8): Shift Clock Input. This clock synchronizes the
serial data transfer.
VCC (Pin 9): Positive Supply. This supply must be kept
free of noise and ripple by bypassing directly to the
analog ground plane.
VREF (Pin 10): Reference Input. The reference input de-
fines the span of the A/D converter and must be kept free
of noise with respect to AGND.
SDI (Pin 5): Digital Data Input. The A/D configuration
word is shifted into this input.
SDO (Pin 6): Digital Data Output. The A/D conversion
result is shifted out of this output.
SCK (Pin 7): Shift Clock Input. This clock synchronizes the
serial data transfer.
VCC (Pin 8): Positive Supply. This supply must be kept
free of noise and ripple by bypassing directly to the
analog ground plane. VREF is tied internally to this pin.
