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.
