ADR435ARMZ-REEL7

Overview

The ADR435ARMZ-REEL7 is a series precision voltage reference from the Analog Devices XFET family, providing a fixed 5.0 V output. It operates within an input voltage range of 7.0 V to 18 V and maintains a maximum supply headroom of 2 V. The device delivers high accuracy with an initial tolerance of ±0.12% (±6 mV) and features a low temperature coefficient of 10 ppm/°C. It supports sourcing up to 30 mA and sinking up to -20 mA while consuming only 800 µA of quiescent current. Noise performance is rated at 8 µV p-p in the 0.1 Hz to 10 Hz band.

Feature Summary

• Utilizes XFET technology for exceptionally low noise and minimal thermal drift curvature correction.
• Capable of both sourcing 30 mA and sinking 20 mA output currents without external components.
• Includes a dedicated trim terminal allowing output voltage adjustment over a ±5% range.
• Requires no external bypass capacitors for stable operation.

Applications

• Precision data acquisition systems
• High resolution data converters
• Medical instruments
• Industrial process control systems

Procurement Notes

Verify the specific suffix 'REEL7' indicates tape-and-reel packaging when ordering. Confirm that the 'ARMZ' designation corresponds to the MSOP-8 package variant. Ensure the component meets RoHS compliance standards required by your manufacturing environment. Cross-reference the manufacturer part number against official distributor catalogs to confirm availability status.

Selection Notes

Select this component when a 5 V reference is required with low noise characteristics suitable for sensitive analog circuits. The A grade specification provides sufficient accuracy for general precision applications. Consider the 2 V minimum headroom requirement to ensure proper regulation across the full operating temperature range.

Part Context

This part belongs to the ADR43x series of ultralow noise XFET voltage references manufactured by Analog Devices. The series includes variants with different fixed output voltages ranging from 2.048 V to 5.000 V. All members share similar electrical characteristics, including low quiescent current and high output drive capability.

Replacement Considerations

The ADR435BRMZ serves as a higher-accuracy alternative within the same series, offering a tighter temperature coefficient of 3 ppm/°C and improved initial accuracy. Both parts utilize identical pin configurations and XFET technology.
