OUTPUT
MODE
Logic Mode Control Pin.
OUTPUT MODE = 0 for CMOS
mode, and OUTPUT MODE =
1 (AVDD1) for LVDS outputs.
6
DFS
Data Format Select Pin.
CMOS control pin that de-
termines the format of the
output data. DFS = high
(AVDD1) for twos comple-
ment, DFS = low (ground) for
offset binary format.
10
SENSE
Reference Mode Selection.
Connect to AGND for internal
1 V reference, and connect to
AVDD2 for external reference.
11
VREF
1.0 V Reference I/O—
Function Dependent on
SENSE. Decouple to ground
with 0.1 μF and 10 μF
capacitors.

REFT
Differential Reference Out-
put. Decoupled to ground
with 0.1 μF capacitor and to
REFB (Pin 14) with 0.1 μF and
10 μF capacitors.
14
REFB
Differential Reference Out-
put. Decoupled to ground
with a 0.1 μF capacitor and to
REFT (Pin 13) with 0.1 μF and
10 μF capacitors.
