REF02CN8

Overview

The REF02CN8#PBF is a precision voltage reference IC from Analog Devices, providing a fixed 5V output. It features an initial accuracy of ±0.3% and a typical temperature coefficient of 5ppm/°C. The device operates with a supply voltage range of 7V to 40V and draws a maximum quiescent current of 1.4mA. It supports a load current up to 20mA and includes a dedicated temperature output pin for absolute temperature sensing. Packaged in an 8-lead plastic DIP (N8), it is rated for operation within the 0°C to 70°C commercial temperature range.

Feature Summary

• Provides stable 5V bandgap reference output with low drift characteristics
• Includes a linear temperature output pin proportional to absolute temperature
• Offers high line rejection and low power consumption suitable for battery applications

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 and RoHS compliance when sourcing. Confirm the N8 package designation matches the required 8-lead plastic DIP footprint for PCB layout. Ensure the operating environment remains within the specified 0°C to 70°C range as defined for this grade. Cross-reference the manufacturer part number against official distributor catalogs to avoid obsolete or non-compliant variants.

Selection Notes

Select this component when a fixed 5V reference with moderate accuracy and low cost is required. It is suitable for applications where low drift and low power are priorities over ultra-high precision. Consider the REF-01 variant if a 10V output is needed instead. For higher accuracy requirements, evaluate alternatives like the LT1019 or LT1021 which offer improved specifications.

Part Context

The REF02CN8 belongs to the REF-01/REF-02 family of precision voltage references manufactured by Analog Devices (formerly Linear Technology). This series is designed for applications requiring stable output voltages over wide operating conditions. The REF-02 specifically provides a 5V output and includes additional functionality such as a temperature sensor output, distinguishing it from the REF-01.

Replacement Considerations

The REF02DN8 is listed as a direct substitute. The REF02EN8 and REF02HN8 are also available within the same package type. For improved performance, the LT1019 is noted as pin-compatible with better specifications.
