AD5726YRSZ-1500RL7

Overview

The AD5726YRSZ-1500RL7 is a quad, 12-bit serial input digital-to-analog converter (DAC) fabricated on iCMOS process technology. It features four buffered voltage outputs with guaranteed monotonicity and ±1 LSB maximum integral nonlinearity (INL). The device supports unipolar or bipolar operation via dual reference inputs (VREFP/VREFN), accommodating supply voltages 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. Key specifications include a settling time of 9 µs to 0.01% for ±2.5 V swings and power dissipation under 240 mW.

Feature Summary

• Quad 12-bit resolution with ±1 LSB max INL and DNL
• Dual reference inputs enable flexible unipolar/bipolar output ranges
• 3-wire serial interface supporting clock rates up to 30 MHz
• Asynchronous CLR function for zero-scale or midscale initialization

Applications

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

Procurement Notes

Verify the specific package variant against the datasheet, as the AD5726 family includes 16-lead SSOP, 20-lead SSOP, and 16-lead SOIC options. Confirm that the Y grade meets the required accuracy specifications for the application. Ensure the ordering suffix corresponds to the desired reel quantity and packaging format before finalizing procurement.

Selection Notes

Select this component when a quad-channel DAC with high voltage capability (+5 V to ±15 V) is required. The external reference configuration allows optimization for specific output swing requirements. Verify that the load capacitance does not exceed typical stability limits (2 nF) if fast settling times are critical. Consider the 3-wire interface compatibility with the host microcontroller's available pins.

Part Context

The AD5726 belongs to Analog Devices' iCMOS series, designed for analog systems requiring higher voltage levels. It serves as the serial-input counterpart to the parallel-input AD5725. The Y grade indicates specific accuracy performance, typically ±0.5 LSB INL at ±15 V supplies. This part is suitable for designs needing integrated buffering without external amplifiers.

Replacement Considerations

The AD5725 is a functional alternative offering parallel input instead of serial. Other quad DACs in the nanoDAC+ family, such as the AD5684R, provide internal references but operate at lower supply voltages (2.7 V to 5.5 V). Verify pinout compatibility and interface differences when substituting.
