AD5726YRSZ-500RL7

Overview

The AD5726YRSZ-500RL7 is a quad, 12-bit serial input voltage output digital-to-analog converter (DAC) fabricated on iCMOS process technology. It features four buffered analog outputs capable of driving loads up to 2 kΩ with ±5 mA current capability under ±15 V supplies. The device supports unipolar or bipolar operation via external reference inputs VREFP and VREFN, allowing flexible output range programming. It operates from single +5 V to ±15 V power supplies and includes a 3-wire serial interface compatible with DSP standards. Key accuracy specifications include ±1 LSB maximum INL and DNL errors, guaranteed monotonicity over temperature, and an asynchronous CLR function for zero-scale or midscale initialization.

Feature Summary

• Quad 12-bit resolution with ±1 LSB max INL/DNL error
• Serial 3-wire interface supporting clock rates up to 30 MHz
• Unipolar/bipolar operation with dual reference inputs (VREFP/VREFN)
• Asynchronous CLR to zero-scale or midscale output

Applications

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

Procurement Notes

Verify the package type matches the specific suffix; YRSZ indicates a 16-lead SSOP package. Confirm the reel quantity corresponds to the RL7 designation. Ensure supply voltages and reference configurations align with the specified operating ranges of +5 V to ±15 V. Check that the industrial temperature range of −40°C to +125°C meets system requirements. Validate pin compatibility with existing PCB layouts due to the 16-lead SSOP form factor.

Selection Notes

Select this component when a quad-channel DAC with high voltage swing and serial control is required. Consider the AD5725 if parallel input interfaces are preferred instead of serial. Ensure the application can accommodate external reference voltages, as the device lacks internal references. Verify that the load capacitance does not exceed typical stability limits to maintain settling time performance. Evaluate power dissipation constraints, particularly at ±15 V supplies where consumption reaches 240 mW.

Part Context

The AD5726 belongs to Analog Devices' iCMOS family, designed for high-performance analog systems requiring higher voltage levels. It serves as the serial-input counterpart to the parallel-input AD5725. The Y grade denotes specific accuracy classifications for INL and DNL. The RSZ suffix identifies the 16-lead SSOP package variant, distinct from SOIC or 20-lead SSOP options available in the broader AD5726 series.

Replacement Considerations

The AD5725 offers identical electrical performance but utilizes a parallel input interface instead of serial. Other ADI quad DACs may require different reference configurations or interface protocols. Verify pinout compatibility before substitution, as package variations exist within the product line.
