REF
(Pin 11)(LTC1093):
Reference Input. The reference
input must be kept free of noise with respect to AGND.
REF

, REF
(Pins 13, 14 )(LTC1094):
Reference Input.
The reference input must be kept free of noise with respect
to AGND.
D
IN
(Pin 12/Pin 15):
Data Input. The A/D configuration
word is shifted into this input.
D
OUT
(Pin 13/Pin 16):
Digital Data Output. The A/D con-
version result is shifted out of this output.
CS (Pin 14/Pin 17):
Chip Select Input. A logic low on this
input enables the LTC1093/LTC1094.
PI FU CTIO S
CLK (Pin 15/Pin 18):
Shift Clock. This clock synchronizes
the serial data transfer.
V
CC
(Pin 16)(LTC1093):
Positive Supply. This supply
must be kept free of noise and ripple by bypassing directly
to the analog ground plane.

CC
(Pins 19, 20)(LTC1094):
Positive Supply.
This supply must be kept free of noise and ripple by
bypassing directly to the analog ground plane. AV
