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.
