VREF (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.
DIN (Pin 12/Pin 15): Data Input. The A/D configuration
word is shifted into this input.
DOUT (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.

CLK (Pin 15/Pin 18): Shift Clock. This clock synchronizes
the serial data transfer.
VCC (Pin 16)(LTC1093): Positive Supply. This supply
must be kept free of noise and ripple by bypassing directly
to the analog ground plane.
AVCC, DVCC (Pins 19, 20)(LTC1094): Positive Supply.
This supply must be kept free of noise and ripple by
bypassing directly to the analog ground plane. AVCC and
DVCC should be tied together on the LTC1094.
