Complete Quad, 14-Bit, High Accuracy,

Serial Input, Bipolar Voltage Output DAC

Preliminary Technical Data

AD5744R

FEATURES

GENERAꢀ DESCRIPTION

Complete quad, 14-bit digital-to-analog

converter (DAC)

Programmable output range: 10 V, 10.2564 V,

or 10.5263 V

1 ꢀSB max INꢀ error, 1 ꢀSB max DNꢀ error

ꢀow noise: 60 nV/√Hz

Settling time: 10 μs max

The AD5744R is a quad, 14-bit, serial input, bipolar voltage

output digital-to-analog converter that operates from supply

voltages of 11ꢀ4 ꢁ up to 1ꢂꢀ5 ꢀ Nominal full-scale output

range is 1ꢃ ꢀ The AD5744R provides integrated output

amplifiers, reference buffers and proprietary power-up/power-

down control circuitryꢀ The parts also feature a digital I/O port,

which is programmed via the serial interface and an analog

temperature sensorꢀ The part incorporates digital offset and

gain adjust registers per channelꢀ

Integrated reference buffers

Internal reference: 10 ppm/°C

On-chip die temperature sensor

Output control during power-up/brownout

Programmable short-circuit protection

Simultaneous updating via ꢀDAC

Asynchronous CꢀR to zero code

Digital offset and gain adjust

The AD5744R is a high performance converter that offers

guaranteed monotonicity, integral nonlinearity (INL) of 1 LSB,

low noise, and 1ꢃ μs settling timeꢀ The AD5744R includes an

on-chip 5 ꢁ reference with a reference tempco of 1ꢃ ppm/°C

maximumꢀ During power-up (when the supply voltages are

changing), ꢁOUT is clamped to ꢃ ꢁ via a low impedance pathꢀ

ꢀogic output control pins

DSP-/microcontroller-compatible serial interface

Temperature range: −40°C to +85°C

iCMOS™ process technology¹

The AD5744R uses a serial interface that operates at clock rates

of up to 3ꢃ MHz and is compatible with DSP and

microcontroller interface standardsꢀ Double buffering allows

the simultaneous updating of all DACsꢀ The input coding is

programmable to either twos complement or offset binary

formatsꢀ The asynchronous clear function clears all DAC

registers to either bipolar zero or zero scale depending on the

coding usedꢀ The AD5744R is ideal for both closed-loop servo

control and open-loop control applicationsꢀ The AD5744R is

available in a 32-lead TQFP, and offers guaranteed

APPꢀICATIONS

Industrial automation

Open-/closed-loop servo control

Process control

Data acquisition systems

Automatic test equipment

Automotive test and measurement

High accuracy instrumentation

specifications over the −4ꢃ°C to +85°C industrial temperature

rangeꢀ See Figure 1, the functional block diagramꢀ

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, and increased ac and dc

performance.
