AD5726YRWZ-REEL

Overview

The AD5726YRWZ-REEL is a quad, 12-bit serial input voltage output digital-to-analog converter (DAC) from Analog Devices. Fabricated on iCMOS process technology, it features guaranteed monotonicity and integral nonlinearity (INL) of ±0.5 LSB maximum at ±15 V supplies. The device supports unipolar or bipolar operation with supply voltages ranging from +5 V to ±15 V. It utilizes a 3-wire serial interface compatible with standard DSP and microcontroller protocols, operating at clock rates up to 30 MHz. Power dissipation is specified at 240 mW maximum with ±15 V supplies.

Feature Summary

• Quad 12-bit resolution with ±0.5 LSB INL and ±1 LSB DNL at ±15 V
• 3-wire serial interface supporting clock rates up to 30 MHz
• Asynchronous CLR function for zero-scale or midscale output reset
• Dual reference inputs (VREFP/VREFN) enabling flexible unipolar/bipolar configurations

Applications

• Industrial automation systems
• Closed-loop servo control applications
• Process control instrumentation
• Automotive test and measurement equipment
• Programmable logic controllers

Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging configuration. Confirm the Y grade designation corresponds to the specific accuracy specifications outlined in the datasheet. Ensure the SOIC-16 package dimensions match the target PCB footprint requirements before integration.

Selection Notes

Select this component when four independent 12-bit channels are required within a single package. The external reference architecture allows optimization of output range without internal resistor temperature coefficient dependencies. Verify that the host controller supports the 3-wire serial protocol timing constraints for reliable data transfer.

Part Context

This part belongs to the AD5726 family of high-voltage DACs. It serves as the serial-input counterpart to the parallel-input AD5725. The Y-grade variant offers improved linearity performance compared to lower grades, specifically targeting precision applications requiring tight error bounds over the industrial temperature range.

Replacement Considerations

The AD5725 is a functional alternative offering parallel input instead of serial. Other quad DACs may require external buffering if current drive capabilities below ±5 mA are insufficient. Package compatibility must be verified when substituting with other SOIC-16 devices.
