REF01EN8

Overview

The REF01EN8 is a precision bandgap voltage reference providing a fixed 10V output with ±0.3% initial accuracy and a typical temperature coefficient of 5ppm/°C. It operates within an input voltage range of 12V to 40V, drawing a maximum quiescent supply current of 1.4mA. The device supports a load current up to 20mA and features low noise performance of 20µVp-p in the 0.1Hz to 10Hz bandwidth. It is housed in an 8-lead plastic DIP package and is guaranteed for operation between 0°C and +70°C.

Feature Summary

• Provides stable 10V output via bandgap architecture
• Ensures high line and load regulation
• Delivers low noise performance suitable for sensitive circuits
• Includes short-circuit protection capabilities

Applications

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

Procurement Notes

Verify the specific suffix EN8 corresponds to the 8-lead PDIP package and 0°C to 70°C operating range. Confirm lead-free finish status (#PBF) if required by assembly specifications. Check manufacturer documentation for any recent production changes or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when a fixed 10V reference is required with moderate accuracy and low power consumption. Consider the REF02 series for a 5V output or the REF01A variant for extended temperature ranges. Ensure input voltage remains within the specified limits to maintain regulation and avoid damage.

Part Context

The REF01EN8 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 reference voltages over varying conditions. The REF-01 specifically provides the 10V output, while the REF-02 offers 5V plus a temperature output pin.

Replacement Considerations

REF01EN8#PBF is listed as a direct substitute.
