REF01J8

Overview

The REF01J8 is a precision series voltage reference integrated circuit manufactured by Analog Devices Inc. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.5%. The device operates within an input voltage range of 12V to 40V and draws a supply current of 1.4mA. It features a temperature coefficient of 8.5ppm/°C and exhibits low noise, specified at 20µVp-p from 0.1Hz to 10Hz. The component supports a maximum output current of 20mA and functions within a commercial operating temperature range of 0°C to 70°C. It is housed in an 8-CDIP package designed for through-hole mounting.

Feature Summary

• Provides a stable 10V fixed output via series regulation architecture
• Ensures high precision with ±0.5% initial accuracy and low temperature drift
• Supports high load capability with 20mA output current drive
• Minimizes low-frequency noise for sensitive analog signal conditioning

Applications

• Precision analog-to-digital converter (ADC) reference sources
• High-resolution digital-to-analog converter (DAC) excitation
• Instrumentation amplifier reference inputs
• Calibration equipment voltage standards

Procurement Notes

Verify the specific suffix J8 confirms the 8-CDIP ceramic dual in-line package and ±0.5% tolerance grade, as other suffixes may indicate different packages or accuracies. Confirm the part status is obsolete and assess availability of direct substitutes like REF01EN8#PBF if long-term supply is required. Ensure environmental compliance documentation matches project requirements.

Selection Notes

Select this component when a 10V fixed reference is required with moderate precision and through-hole packaging. Compare against REF01EN8 for higher accuracy (±0.3%) or REF01CPZ for surface mount options. Evaluate the 8.5ppm/°C temperature coefficient against system thermal stability needs. Consider the 1.4mA quiescent current impact on total power budget.

Part Context

The REF01J8 belongs to the REF01 family of precision voltage references from Analog Devices. This series is designed for applications requiring stable, low-noise voltage sources. The J8 suffix specifically denotes the ceramic DIP package variant with ±0.5% accuracy, distinguishing it from plastic DIP or surface mount versions within the same functional family.

Replacement Considerations

REF01EN8#PBF is listed as a direct substitute offering improved ±0.3% accuracy in an 8-DIP package. REF01CPZ and REF01HPZ are available as similar alternatives, potentially differing in package type or specific performance metrics.
