DAC714
16-Bit DIGITAL-TO-ANALOG CONVERTER
With Serial Data Interface
DESCRIPTION
The DAC714 is a complete monolithic digital-to-
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 3
limit. Not 100% tested for this parameter. (5) For the worst-case Binary Two's Complement code changes: FFFF

. (6) During power supply turn on, the transient supply current may approach 3x the maximum quiescent specification. (7) Typical (i.e. rated) supply voltages times maximum currents.

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.
