REF02HN8#PBF

Overview

The REF02HN8#PBF is a precision voltage reference IC from the Analog Devices REF-02 series, housed in an 8-pin plastic DIP package. It provides a fixed 5V output with a tolerance of ±0.5%. The device operates within an input voltage range of 7V to 40V and draws a maximum quiescent supply current of 1.4mA. It features a typical temperature coefficient of 25ppm/°C and low noise characteristics of 10µVp-p in the 0.1Hz to 10Hz band. The component supports a load current of up to 20mA and includes a dedicated temperature output pin.

Feature Summary

• Includes a dedicated temperature output pin providing a linear voltage proportional to absolute temperature
• Features high line rejection and low power consumption suitable for battery-operated systems
• Provides stable output voltages over a wide range of operating conditions

Applications

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

Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish compliance when sourcing. Confirm the N8 package designation matches the required 8-lead plastic DIP footprint for PCB layout. Ensure the H grade specifications align with the intended operational temperature range requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring moderate accuracy and low drift at a lower cost point compared to higher-grade references. Consider the REF-02 series for designs needing a built-in temperature sensor output. Evaluate the 20mA sink capability against load requirements to ensure adequate drive strength without exceeding thermal limits.

Part Context

This part belongs to the REF-01/REF-02 family of precision bandgap references manufactured by Analog Devices Inc. The REF-02 variant specifically offers a 5V output and an additional temperature sensing pin, distinguishing it from the REF-01 which lacks this feature. These devices are designed as cost-effective solutions for general-purpose precision applications.
