AD5726YRWZ-REEL7

Overview

The AD5726YRWZ-REEL7 is a quad, 12-bit serial input voltage output digital-to-analog converter (DAC) fabricated on iCMOS process technology. It features guaranteed monotonicity and integral nonlinearity (INL) of ±1 LSB maximum. 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 DSP and microcontroller standards, operating at clock rates up to 30 MHz. Power dissipation is less than 240 mW with ±15 V supplies. The component is housed in a 16-lead SOIC package and operates over an industrial temperature range of −40°C to +125°C.

Feature Summary

• Quad 12-bit resolution with ±1 LSB maximum INL and DNL errors
• Unipolar/bipolar voltage output capability via dual reference inputs (VREFP/VREFN)
• 3-wire serial interface supporting clock rates up to 30 MHz
• Asynchronous CLR function for zero-scale or midscale output reset

Applications

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

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the reel packaging configuration as defined by Analog Devices. Confirm that the Y grade specification meets the required accuracy parameters for the intended application. Ensure compatibility with the host system's voltage levels and serial communication protocols before integration.

Selection Notes

Select this component when a quad-channel DAC with high voltage operation (up to ±15 V) is required. The external reference configuration allows flexibility in setting output ranges. Consider the 16-lead SOIC package dimensions for PCB layout. Verify that the load capacitance does not exceed stability limits, as excessive capacitance increases settling time.

Part Context

The AD5726 series includes variants such as the AD5725, which offers parallel input instead of serial. The Y grade indicates specific accuracy performance regarding INL and DNL. The REEL7 suffix denotes the tape and reel packaging format containing 400 units per reel, distinct from cut tape or other packaging options available for the same functional device.

Replacement Considerations

The AD5725 serves as a parallel-input alternative within the same family. When replacing, verify pinout compatibility between the 16-lead SOIC packages. Ensure the replacement part supports the required supply voltage range and serial interface timing specifications.
