REF02CN8#PBF

Overview

The REF02CN8#PBF is a precision 5V bandgap voltage reference in an 8-lead plastic DIP package. It provides stable output accuracy of ±0.3% with a typical temperature coefficient of 5ppm/°C. The device features low noise (10µVp-p from 0.1Hz to 10Hz) and high line rejection. It includes a dedicated temperature output pin providing a linear voltage proportional to absolute temperature. Operating supply current is limited to 1.4mA maximum, supporting input voltages from 7V to 40V.

Feature Summary

• Includes a dedicated temperature output pin for linear voltage proportional to absolute temperature
• Provides stable 5V output with trimmed initial accuracy of ±0.3%
• Features low power consumption with maximum quiescent supply current of 1.4mA

Applications

• A/D and D/A converters
• Precision regulators
• Constant current sources
• Bridge excitation circuits

Procurement Notes

Verify the specific suffix CN8 corresponds to the 8-lead plastic DIP package and 0°C to 70°C operating temperature range. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration into production designs.

Selection Notes

Select this component when a fixed 5V reference with moderate accuracy and low drift is required. The inclusion of a temperature output pin distinguishes it from similar references lacking this feature. Ensure input voltage remains within the specified 7V to 40V range for proper regulation.

Part Context

This part belongs to the REF-01/REF-02 family of precision bandgap references manufactured by Analog Devices. The REF-02 variant specifically offers the 5V output level and additional temperature sensing capability compared to the 10V REF-01 model.

Replacement Considerations

LT1019 is listed as a related part offering improved specifications including 0.05% accuracy and 5ppm/°C drift.
