DESCRIPTION
The DAC714 is a complete monolithic digital-toanalog converter including a +10V temperature compensated reference, current-to-voltage amplifier, a
high-speed synchronous serial interface, a serial output which allows cascading multiple converters, and
an asynchronous clear function which immediately
sets the output voltage to midscale.
The output voltage range is ±10V, ±5V, or 0 to +10V
while operating from ±12V or ±15V supplies. The
gain and bipolar offset adjustments are designed so
that they can be set via external potentiometers or
external D/A converters. The output amplifier is protected against short circuit to ground.
The 16-pin DAC714 is available in a plastic 0.3" DIP,
ceramic 0.3" CERDIP, and wide-body plastic SOIC
package. The DAC714P, U, HB, and HC are specified
over the –40°C to +85°C temperature range while the
DAC714HL is specified over the 0°C to +70°C range.

ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from performance degradation to complete device failure. BurrBrown Corporation recommends that all integrated circuits
be handled and stored using appropriate ESD protection
methods.
ESD damage can range from subtle performance degradation 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.
