Preliminary Technical Data
AD5722/AD5732/AD5752
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 AD5722/AD5732/AD5752 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-scale
INL error: 16 LSB maximum, DNL error: 1 LSB maximum
Total unadjusted error (TUE): 0.1% FSR maximum
Settling time: 10 µs maximum
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.
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
The parts offer guaranteed monotonicity, integral nonlinearity
(INL) of 16 LꢀB maximum, low noise, and 10 µs maximum
settling time.
The AD5722/AD5732/AD5752 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

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.
