GENERAL DESCRIPTION
The AD5724/AD5734/AD5754 are quad, 12-/14-/16-bit, serial
input, voltage output DACs. The devices 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 devices 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 devices 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 that 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.
