ADR02AR-REEL7

Overview

The ADR02AR-REEL7 is a precision series voltage reference from Analog Devices, delivering a fixed 5V output. It features an initial accuracy of 0.1% and a temperature coefficient of 10 ppm/°C. The device operates within an input voltage range of 7V to 36V and draws a supply current of 1 mA. It provides a maximum shunt current of 10 mA without requiring external capacitors for stability. Noise performance is specified at 10 µV p-p over the 0.1 Hz to 10 Hz bandwidth. Line regulation is 30 ppm/V, and load regulation is 70 ppm/mA. It is housed in an 8-pin NSOIC package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-precision 5V reference with low temperature drift
• Operates stably without external bypass capacitors
• Includes dedicated pins for temperature sensing and output trimming

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converters
• Industrial process control instrumentation
• Automatic battery monitoring circuits

Procurement Notes

Verify the specific suffix against official documentation, as REEL7 indicates tape-and-reel packaging which may differ from bulk or cut-tape variants. Confirm that the 'AR' designation corresponds to the standard 10 ppm/°C grade rather than higher precision options. Ensure the component matches the required 8-pin SOIC footprint and thermal specifications for the target application environment.

Selection Notes

Select this component when a stable 5V reference is required with moderate precision and wide operating voltage headroom. It is suitable for designs prioritizing low power consumption and simplified circuitry due to capacitor-free operation. Consider alternative grades if tighter temperature coefficients or lower noise levels are necessary for the specific measurement requirements.

Part Context

This part belongs to the ADR02 family of super-miniature precision voltage references. It serves as a drop-in replacement for legacy industry-standard REF02 devices while offering improved performance characteristics. The series is designed for applications demanding compact form factors and reliable long-term stability in harsh industrial environments.

Replacement Considerations

Officially documented direct replacements include the ADR02AKS-REEL7 and ADR02AUJZ-REEL7, which offer similar functionality in different package formats.
