REF02DN8#PBF

Overview

The REF02DN8#PBF is a precision voltage reference IC from the Analog Devices REF-02 series, housed in an 8-lead plastic DIP package. It provides a fixed 5V output with a tolerance of ±2%. The device operates within an input voltage range of 7V to 40V and draws a maximum quiescent supply current of 1.4mA. It supports a load current of up to 20mA and features a temperature output pin providing a linear voltage proportional to absolute temperature. The unit is guaranteed for operation over a commercial temperature range of 0°C to 70°C.

Feature Summary

• Provides a stable 5V bandgap reference output suitable for precision applications
• Includes a dedicated temperature output pin for linear voltage proportional to absolute temperature
• Features low power consumption with a maximum quiescent supply current of 1.4mA
• Offers high line rejection and low noise characteristics for sensitive circuitry

Applications

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

Procurement Notes

Verify the specific suffix DN8 corresponds to the 8-lead plastic DIP package and the 0°C to 70°C operating temperature range. Confirm that the ±2% accuracy class meets the design requirements, as other variants like HN8 offer tighter tolerances. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this part when a fixed 5V reference with moderate accuracy (±2%) is sufficient. Consider the REF02HN8#PBF if tighter accuracy (±0.5%) or lower drift is required. Verify that the 20mA load current capability aligns with the application's sink and source needs. Ensure the 7V minimum input voltage requirement fits the system power budget.

Part Context

The REF02DN8#PBF belongs to the REF-01/REF-02 family of precision voltage references manufactured by Analog Devices Inc. This series utilizes bandgap technology to deliver stable outputs across varying conditions. The REF-02 variant specifically includes a temperature output feature, distinguishing it from the REF-01. The N8 package designation indicates an 8-lead plastic dual in-line configuration.

Replacement Considerations

REF02HN8#PBF is listed as a similar alternative offering higher accuracy.
