AGND
DIFF
GAIN
Analog Ground.
Output of Signal Input Preamplifier.
Connect GAIN Pin to DIFF for
nominal
×
1. Gains greater than
1 can be resistively scaled.
Do not leave unconnected.
Denotes A or B lines loss of
connection and/or loss of reference
to transducer or converter.
16-bit serial data output 13 bits of
absolute position information plus
overrange and underrange plus LOS.
Serial Clock. Maximum rate = 2 MHz.
Chip Select. Loads serial interface
with current positional information
and enable output.
Two pins that denote whether the
input signals are underrange or
overrange.
Updates every LSB.
Denotes Null Position.
Indicates direction. DIR is HI for
positive displacement and LO for
negative displacement.
Digital Ground.

VCO GAIN
Sets the VCO gain internally.
Connect to VEL for 2400 LSB/s.
Disconnect for 800 LSB/s.
INTIN
Determines system dynamics connect
C and RC (serial) parallel
combination across INTIN and
VEL to determine loop dynamics.
VEL
Analog Velocity Output.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD2S93 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the
operational section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
