GENERAL DESCRIPTION
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.
The parts offer guaranteed monotonicity, integral nonlinearity
(INL) of ±16 LSB maximum, low noise, and 10 μs typical
settling time.
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
output (depending on the state of Pin BIN/2sComp), and
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
16-bit, serial input, unipolar/bipolar voltage output DACs.

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, as well as increased ac and dc performance.
