AD5726YRSZ-REEL

Overview

The AD5726YRSZ-REEL 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 ±0.5 LSB maximum at ±15 V supplies, or ±1 LSB at single +5 V operation. The device supports unipolar or bipolar outputs via external reference inputs VREFP and VREFN. It operates from supply voltages ranging from +5 V to ±15 V with power dissipation under 240 mW at ±15 V. The part includes double-buffered inputs, an asynchronous CLR function for zero-scale or midscale reset, and a 3-wire serial interface compatible with DSP standards.

Feature Summary

• Quad 12-bit resolution with ±0.5 LSB INL at ±15 V supplies
• Unipolar/bipolar voltage output configurable via dual reference inputs
• 3-wire serial interface supporting clock rates up to 30 MHz
• Asynchronous CLR to zero-scale or midscale output

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 required for the application. Ensure the SSOP-16 package variant matches the PCB footprint design constraints.

Selection Notes

Select this component when four independent 12-bit channels are required in a compact surface-mount package. Verify that the external reference voltage source can handle the current sourcing and sinking requirements of the VREFP pin. Ensure the system operates within the specified temperature range of −40°C to +125°C.

Part Context

This part belongs to the AD5726 family of high-voltage DACs. It is distinct from the parallel-input AD5725. The Y grade offers tighter linearity specifications compared to other grades. The REEL suffix denotes bulk reel packaging for automated assembly processes.

Replacement Considerations

The AD5725BRSZ is a parallel input alternative. Verify interface compatibility changes when substituting serial devices with parallel counterparts.

FAQ

How is the output voltage range configured?

The output range is set by the voltages applied to the VREFP and VREFN pins. Unipolar positive output occurs when VREFN is 0 V and VREFP is positive.

What is the maximum serial clock rate?

The serial interface supports clock rates up to 30 MHz.

Is the device guaranteed monotonic?

Yes, the AD5726 is guaranteed monotonic over the full operating temperature range due to its ±1 LSB maximum DNL specification.
