REF01J

Overview

The REF01J is a precision series voltage reference IC manufactured by Analog Devices Inc. It provides a fixed output voltage of 10 V with an initial accuracy tolerance of ±0.5%. The device features a temperature coefficient of 25 ppm/°C and operates within a junction-to-ambient thermal range from 0°C to +70°C. It requires a minimum input voltage of 13 V and supports a maximum input voltage of 33 V. The unit draws a supply current of 1.4 mA and delivers a maximum load current of 21 mA. Noise performance is specified at 20 µVp-p over the 0.1 Hz to 10 Hz frequency band. The component is housed in an 8-SOIC surface-mount package.

Feature Summary

• Provides a stable 10 V fixed output via a series reference architecture
• Delivers low noise performance suitable for sensitive analog circuits
• Supports high load currents up to 21 mA for direct drive applications

Applications

• Precision data acquisition systems requiring stable reference voltages
• High-resolution analog-to-digital converter (ADC) references
• Calibration equipment and test instrumentation
• Industrial process control signal conditioning

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm pinout compatibility, package dimensions, and electrical tolerances. Ensure that the operating environment remains within the specified 0°C to +70°C temperature range to maintain rated accuracy. Confirm RoHS compliance status if required by assembly specifications.

Selection Notes

Select this component when a 10 V output is required with moderate precision and low noise characteristics. Consider the 25 ppm/°C temperature coefficient for thermal stability requirements. Evaluate the 1.4 mA quiescent current against power budget constraints. Compare against other REF01 variants if tighter accuracy or different packaging options are needed.

Part Context

The REF01J belongs to the REF01 family of precision voltage references produced by Analog Devices Inc. This series is designed for applications demanding high stability and low drift. The J suffix typically denotes a specific accuracy grade and package configuration within the broader product line, distinguishing it from other variants like the REF01CP or REF01HSA+.

Replacement Considerations

Direct replacements include REF01HSA+, REF01EN8, and REF01CPZ. Verify pinout compatibility and electrical parameter alignment before substitution.
