GENERAL DESCRIPTION
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-
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 LSB 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
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 mid-scale output. The parts are available in a 24-lead TSSOP
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.
