Preliminary Technical Data  
AD5722R/AD5732R/AD5752R  
FEATURES  
GENERAL DESCRIPTION  
Complete, dual, 12-/14-/16-bit D/A converter  
Operates from single/dual supplies  
Software programmable output range  
+5 V, +10 V, +10.8 V, 5 V, 10 V, 10.8 V  
The AD5722R/AD5732R/AD5752R are dual, 12-/14-/16-bit,  
serial input, voltage output, digital-to-analog converters. They  
operate from single supply voltages of +4.5 V up to +16.5 V or  
dual supply voltages from 4.5 V up to 16.5 V. Nominal full-  
INL error: 16 LSB maximum, DNL error: 1 LSB maximum  
Total unadjusted error (TUE): 0.1% FSR maximum  
Settling time: 10 µs maximum  
Integrated reference: 5 ppm/°C typ.  
Integrated reference buffers  
Output control during power-up/brownout  
Simultaneous updating via LDAC  
Asynchronous CLR to zero-/mid-scale  
DSP-/microcontroller-compatible serial interface  
24-lead TSSOP  
scale output range is software-selectable from the options of  
+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.  
The parts offer guaranteed monotonicity, integral nonlinearity  
(INL) of 16 LꢀB maximum, low noise, 10 µs maximum settling  
time, and an on-chip +2.5 V reference.  
The AD5722R/AD5732R/AD5752R use a serial interface that  
operates at clock rates up to 30 MHz and are compatible with  
DꢀP 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  
Operating temperature range: −40°C to +85°C

straight binary for a unipolar output. The asynchronous clear  
function clears all DAC registers to a user-selectable zero-scale  
or mid-scale output. The parts are available in a 24-lead TꢀꢀOP  
and offer guaranteed specifications over the −40°C to +85°C  
industrial temperature range.

1 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 30 V and operating at ±15 V supplies while allowing dramatic reductions in power consumption and  
package size, and increased AC and DC performance.
