REF02BIHP

Overview

The REF02BIHP is a precision voltage reference from Analog Devices Inc., providing a stable +5V output. It features an initial accuracy of ±0.5% and a temperature coefficient of 25 ppm/°C. The device operates within a supply voltage range of 7V to 40V and supports a maximum shunt current of 10 mA. Designed for through-hole mounting, it utilizes an 8-pin DIP package. The operational temperature range spans from -40°C to +85°C, ensuring reliability in industrial environments.

Feature Summary

• Provides a stable +5V output with minimal effect on adjustment ranges
• Features low temperature coefficient for high thermal stability
• Supports wide input voltage range for flexible power supply integration

Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• Instrumentation amplifier biasing
• Data acquisition systems requiring high stability

Procurement Notes

Verify the specific suffix 'BIHP' against official Analog Devices documentation to confirm pinout compatibility and RoHS status, as legacy markings may vary. Ensure the procurement channel provides valid traceability for military or aerospace specifications if required by the application design. Cross-reference the datasheet revision date to confirm current manufacturing parameters.

Selection Notes

Select this component when a fixed 5V reference with ±0.5% initial accuracy is required. The 25 ppm/°C temperature coefficient makes it suitable for applications demanding moderate thermal stability. Consider the 8-pin DIP package for prototyping or through-hole PCB designs where surface-mount options are not feasible. Verify input voltage constraints against the system power rail.

Part Context

The REF02 series represents a family of precision three-terminal voltage references manufactured by Analog Devices. These devices are designed to offer superior performance compared to standard zener diodes, providing lower noise and better long-term stability. The REF02BIHP variant specifically targets applications requiring robust performance across extended temperature ranges.

Replacement Considerations

Official substitutes include REF02CPZ and REF02HPZ from Analog Devices. Verify pin compatibility and package dimensions before substitution. Ensure that the alternative part meets the specific temperature coefficient and accuracy requirements of the original design.
