Serial Input, Bipolar Voltage Output DAC

CMOS^TM

Preliminary Technical Data

AD5744/AD5764

FEATURES

GENERAꢀ DESCRIPTION

Complete quad 14/16-bit D/A converter

Programmable output range: 10 V, 10.25 V, or 10.5 V

1 ꢀSB max INꢀ error, 1 ꢀSB max DNꢀ error

ꢀow noise : 60 nV/√Hz

The AD5744/64 is a quad, 14/16-bit serial input, voltage output

digital-to analog converter that operates from supply voltages of

1ꢀ ꢁ up to 15 ꢁ. Nominal full-scale output range is 1ꢂ ꢁ,

provided are integrated output amplifiers, reference buffers,

internal reference, and proprietary power-up/power-down

control circuitry. It also features a digital I/O port that may be

programmed via the serial interface, and an analog temperature

sensor. The part incorporates digital offset and gain adjust

registers per channel.

Settling time: 10µs max

Integrated reference buffers

Internal reference, 10 ppm/°C

On-chip temp sensor, 5°C accuracy

Output control during power-up/brownout

Programmable short-circuit protection

Simultaneous updating via ꢀDAC

The AD5744/64 is a high performance converter that offers

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

low noise and 1ꢂ µs settling time and includes an on-chip 5 ꢁ

reference with a reference tempco of 1ꢂ ppm/°C max. During

power-up (when the supply voltages are changing), ꢁout is

clamped to ꢂꢁ via a low impedance path.

CꢀR

Asynchronous

to zero code

Digital offset and gain adjust

ꢀogic output control pins

DSP/microcontroller compatible serial interface

Temperature range:−40°C to +85°C

iCMOS™ Process Technology

The AD5744/64 uses a serial interface that operates at clock rates

of up to 3ꢂ MHz and is compatible with DSP and microcontroller

interface standards. Double buffering allows the simultaneous

updating of all DACs. The input coding is programmable to either

twos complement or Offset binary formats. The asynchronous

clear function clears all DAC registers to either bipolar zero or

zero-scale depending on the coding used. The AD5744/64 is ideal

for both closed-loop servo control and open-loop control

applications. The AD5744/64 is available in a 3ꢀ-lead TQFP

package, and offers guaranteed specifications over the −4ꢂ°C to

+85°C industrial temperature range. See functional block

diagram, Figure 1.

iCMOS™ Process Technology

For 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 30V and operating at +/-15V supplies while allowing dramatic reductions in

power consumption and package size, and increased AC and DC performance.
