PIN FUNCTIONS
become parallel logic inputs that control a reduced set of
the A/D operating modes. PAR/SER should be connected
directly to ground or the V
by a logic signal.

with a 1μF ceramic capacitor, nominally 1.25V.
SENSE (Pin 50): Reference Programming Pin. Connecting
SENSE to V
range. Connecting SENSE to ground selects the internal
reference and a ±0.5V input range. An external reference
between 0.625V and 1.3V applied to SENSE selects an
input range of ±0.8 • V
Exposed Pad (Pin 53): Ground. The Exposed Pad must
be soldered to the PCB ground.
LVDS Outputs
All pins in this section are differential LVDS outputs.
The output current level is programmable. There is an
optional internal 100Ω termination resistor between
the pins of each LVDS output pair.
