Complete, Dual, 12-/14-/16-Bit, Serial

Input, Unipolar/Bipolar, Voltage Output DACs

AD5722/AD5732/AD5752

GENERAL DESCRIPTION

FEATURES

Complete, dual, 12-/14-/16-bit digital-to-analog converter (DAC)

Operates from single/dual supplies

The AD5722/AD5732/AD5752 are dual, 12-/14-/16-bit, serial

input, voltage output, digital-to-analog converters. They operate

from single-supply voltages from +4.5 V up to +16.5 V or dual-

supply voltages from 4.5 V up to 16.5 V. Nominal full-scale

output range is software-selectable from +5 V, +10 V, +10.8 V,

5 V, 10 V, or 10.8 V. Integrated output amplifiers, reference

buffers, and proprietary power-up/power-down control circuitry

are also provided.

Software programmable output range

+5 V, +10 V, +10.8 V, 5 V, 10 V, 10.8 V

INL error: 16 LSB maximum, DNL error: 1 LSB maximum

Total unadjusted error (TUE): 0.1% FSR maximum

Settling time: 10 µs typical

Integrated reference buffers

Output control during power-up/brownout

The parts offer guaranteed monotonicity, integral nonlinearity

(INL) of 16 LSB maximum, low noise, and 10 µs typical

settling time.

iCMOS process technology¹

The AD5722/AD5732/AD5752 use a serial interface that

operates at clock rates up to 30 MHz and are compatible with

DSP and microcontroller interface standards. Double buffering

allows the simultaneous updating of all DACs. The input coding

is user-selectable twos complement or offset binary for a bipolar

straight binary for a unipolar output. The asynchronous clear

function clears all DAC registers to a user-selectable zero-scale

or midscale output. The parts are available in a 24-lead TSSOP

and offer guaranteed specifications over the −40°C to +85°C

industrial temperature range.

The AD5722/AD5732/AD5752 are pin compatible with the

AD5724/AD5734/AD5754, which are complete, quad, 12-/14-/

16-bit, serial input, unipolar/bipolar voltage output DACs.

¹For analog systems designers within industrial/instrumentation equipment OEMs who need high performance ICs at higher voltage levels, iCMOS® is a technology

platform that enables the development of analog ICs capable of 30 V and operating at 15 V supplies while allowing dramatic reductions in power consumption and

package size, as well as increased ac and dc performance.
