ANALOG DEVICES AD5722R AD5732R AD5752R Data Sheet Manual

Complete, Dual, 12-/14-/16-Bit, Serial Input, Unipolar/Bipolar, Voltage Output DACs

Preliminary Technical Data AD5722R/AD5732R/AD5752R FEATURES GENERAL DESCRIPTION Complete, dual, 12-/14-/16-bit D/A converter The AD5722R/AD5732R/AD5752R are dual, 12-/14-/16-bit, Operates from single/dual supplies serial input, voltage output, digital-to-analog converters. They Software programmable output range operate from single supply voltages of +4.5 V up to +16.5 V or +5 V, +10 V, +10.8 V, ±5 V, ±10 V, ±10.8 V dual supply voltages from ±4.5 V up to ±16.5 V. Nominal full- INL error: ±16 LSB maximum, DNL error: ±1 LSB maximum scale output range is software-selectable from the options of Total unadjusted error (TUE): 0.1% FSR maximum +5 V, +10 V, +10.8 V, ±5 V, ±10 V, or ±10.8 V. Integrated output Settling time: 10 µs maximum amplifiers, reference buffers, and proprietary power-up/power- Integrated reference: 5 ppm/°C typ. down control circuitry are also provided. Integrated reference buffers

The parts offer guaranteed monotonicity, integral nonlinearity

time, and an on-chip +2.5 V reference.

Asynchronous CLR to zero-/mid-scale

The AD5722R/AD5732R/AD5752R use a serial interface that

DSP-/microcontroller-compatible serial interface

operates at clock rates up to 30 MHz and are compatible with

24-lead TSSOP

Operating temperature range: −40°C to +85°C DSP and microcontroller interface standards. Double buffering i CMOS™ process technology1 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/2s Comp), and

Industrial automation straight binary for a unipolar output. The asynchronous clear Closed-loop servo control, process control function clears all DAC registers to a user-selectable zero-scale Automotive test and measurement or mid-scale output. The parts are available in a 24-lead TSSOP Programmable logic controllers and offer guaranteed specifications over the −40°C to +85°C

industrial temperature range.
