DESCRIPTION
Positive supply pin for logic circuits. Connect to +V_CC.
Connect Pin 2 or Pin 3 to Pin 9 (V_OUT) for a 20V
FSR. Connect both to Pin 9 for a 10V FSR.
Bipolar offset. Connect to Pin 6 (V_{REF OUT}) through
100Ω resistor or 200Ω potentiometer for bipolar
operation.
Analog common, ±V_CC supply return.
+10V reference output referred to ACOM.
Connected to V_{REF OUT} through a 1kΩ gain
adjustment potentiometer or a 500Ω resistor.
Analog supply input, nominally +12V to +15V
referred to ACOM.
D/A converter voltage output.
Analog supply input, nominally –12V or –15V
referred to ACOM.
Master enable for LDAC, LLSB, and LMSB. Must
be low for data transfer to any latch.
Load DAC. Must be low with WR for data transfer
to the D/A latch and simultaneous update of the
D/A converter.
When low, resets the D/A latch such that a Bipolar
Zero output is produced. This control overrides all
other data input operations.
Enable for 4-bit input latch of D₈-D₁₁ data inputs.
NOTE: This logic path is slower than the WR path.
Enable for 8-bit input latch of D₀-D₇ data inputs.
NOTE: This logic path is slower than the WR path.

NOTE: (1) Stresses above those listed under “Absolute Maximum Ratings”
may cause permanent damage to the device. Exposure to absolute maximum
conditions for extended periods may affect device reliability.
ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from per-
formance degradation to complete device failure. Burr-
Brown Corporation recommends that all integrated circuits
be handled and stored using appropriate ESD protection
methods.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet
published specifications.
