ADR02AR-REEL

Overview

The ADR02AR-REEL is a precision bandgap voltage reference from Analog Devices, providing a fixed 5.0 V output. It features an initial accuracy of ±0.1% and a temperature coefficient of 10 ppm/°C. The device operates within a supply voltage range of 7.0 V to 36.0 V and delivers a maximum output current of 10 mA without requiring external capacitors. It exhibits low noise performance of 10 μV p-p (0.1 Hz to 10.0 Hz) and line regulation of 30 ppm/V. The component is housed in an 8-lead NSOIC package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Ultracompact design with high stability and low power consumption
• Pin-compatible drop-in replacement for industry standard REF02 devices
• Integrated external buffer and simple resistor network for output trimming

Applications

• Precision data acquisition systems
• High resolution analog-to-digital converters
• Industrial process control systems
• Precision instruments and measurement equipment

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and reel specifications. Ensure the ordering part number matches the required tolerance and thermal grade. Confirm availability status as distribution channels may list limited stock or obsolete statuses. Cross-reference the manufacturer date code if long-term reliability is critical for the application.

Selection Notes

Select this component when a stable 5 V reference is required in space-constrained designs. The 8-lead SOIC package offers a direct pin-for-pin upgrade path for legacy REF02 implementations. Consider the 10 ppm/°C drift specification for applications operating across wide industrial temperature ranges. The 10 mA output capability supports moderate load requirements without additional buffering circuitry.

Part Context

The ADR02AR-REEL belongs to the ADR0x family of precision voltage references, which includes variants offering 2.5 V, 3.0 V, and 10.0 V outputs. This series is characterized by its small footprint options, including SC70 and TSOT packages alongside the standard SOIC form factor. The family is designed to replace older generation references while providing improved noise and stability characteristics.

Replacement Considerations

The datasheet explicitly identifies the ADR02 series as a drop-in replacement for the industry-standard REF02. Verify that the legacy REF02 pinout matches the ADR02 configuration before substitution.
