.. plete, Dual, 12-/14-/16-Bit, Serial Input, Unipolar/Bipolar, Voltage Output DACs AD5722/AD5732/AD5752 Features plete, 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 to zero scale or midscale DSP-/microcontroller-patible serial interface 24-lead TSSOP Operating temperature range: - 40°C to +85°C i CMOS process technology1 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 dualsupply 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 patible with DSP and microcontroller interface standards. Double buffering allows the simultaneous updating of all DACs. The input coding is user-selectable twos plement or offset binary for a bipolar output (depending on the state of Pin BIN/2sp), 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...
