FEATURES Complete, dual, 12-/14-/16-bit digital-to-analog converter (DAC) Operates from single/dual supplies Software programmable output range +5 V, +10 V, +10.8 V, ±5 V, ±10 V, ±10.8 V INL error: ±16 LSB maximum, DNL error: ±1 LSB maximum Total unadjusted error (TUE): 0.1% FSR maximum Settling time: 10 µs typical Integrated reference buffers Output control during power-up/brownout Simultaneous updating via LDAC Asynchronous CLR APPLICATIONS to zero scale or midscale DSP-/microcontroller-compatible serial interface 24-lead TSSOP Operating temperature range: −40°C to +85°C i CMOS process technology1 Industrial automation Closed-loop servo control, process control Automotive test and measurement Programmable logic controllers 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 The AD5722/AD5732/AD5752 are pin compatible with the ), 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. AD5724/AD5734/AD5754, which are complete, quad, 12-/14-/ 16-bit, serial input, unipolar/bipolar voltage output DACs.
