analog converter including a +10V temperature com-
pensated reference, current-to-voltage amplifier, a
high-speed synchronous serial interface, a serial out-
put 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 pro-
tected 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.

NOTES: (1) Digital inputs are TTL and +5V CMOS compatible over the specification temperature range. (2) FSR means Full Scale Range. For example, for
±10V
output, FSR = 20V. (3) Errors
externally adjustable to zero. (4) Maximum represents the 3σ limit. Not 100% tested for this parameter. (5) For the worst-case Binary Two’s Complement code changes: FFFF

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.
