GENERAL DESCRIPTION
The AD5724/AD5734/AD5754 are quad, 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 maximum
settling time.
The AD5724/AD5734/AD5754 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.

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.
