REF02DN8#PBF

Overview

The REF02DN8#PBF is a precision series voltage reference manufactured by Analog Devices, formerly Linear Technology. It provides a fixed 5V output with an initial accuracy of ±0.3% and a typical temperature coefficient of 5ppm/°C. The device operates within an input voltage range of 7V to 40V and draws a maximum supply current of 1.4mA. It features a low noise profile of 3ppm peak-to-peak and includes a dedicated temperature output pin proportional to absolute temperature. The component is housed in an 8-DIP package and supports through-hole mounting.

Feature Summary

• Provides stable 5V output via bandgap reference technology
• Includes a linear temperature output pin for absolute temperature sensing
• Offers high line rejection and low power consumption

Applications

• Precision measurement systems requiring stable voltage references
• Data acquisition circuits needing low drift performance
• Temperature sensing applications utilizing the proportional output pin

Procurement Notes

Verify the manufacturer designation carefully, as Analog Devices acquired Linear Technology. Ensure the specific suffix matches the required package type. Confirm RoHS compliance status for the specific production lot. Check for obsolescence notices or PCN updates regarding the PDIP package. Validate that the supplier source is authorized to prevent counterfeit components.

Selection Notes

Select this component when a fixed 5V reference with moderate accuracy is sufficient. Consider the REF02HN8#PBF if tighter initial accuracy is required. Evaluate the REF01 series if a 10V output is needed instead. Ensure the application can accommodate the through-hole DIP package constraints. Verify that the temperature output feature aligns with system design requirements.

Part Context

This part belongs to the REF-01/REF-02 family of precision voltage references. These devices are designed for applications where low drift, moderate accuracy, and low cost are primary considerations. The REF-02 variant specifically adds a temperature output capability not present in the REF-01. They serve as fundamental building blocks for analog signal conditioning and conversion stages.

Replacement Considerations

• REF02HN8#PBF
• REF02EN8#PBF

FAQ

Does the REF02DN8#PBF include a shutdown function?

No, the REF02DN8#PBF does not include a shutdown pin; it operates continuously once powered.

What is the purpose of the additional pin on the REF02 compared to standard references?

The REF02 includes a dedicated temperature output pin that provides a linear voltage proportional to absolute temperature.
