REF01HP

Overview

The REF01HP is a precision series voltage reference integrated circuit manufactured by Analog Devices Inc. It provides a fixed 10V output with an initial accuracy tolerance of ±0.5%. The device operates within an input voltage range of 13V to 33V and draws a supply current of 1.4mA. It features a low temperature coefficient of 25ppm/°C and exhibits noise levels of 30µVp-p in the 0.1Hz to 10Hz frequency band. Designed for through-hole mounting, it is housed in an 8-PDIP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Delivers a stable 10V fixed output via a series reference architecture
• Maintains high precision with ±0.5% initial accuracy tolerance
• Ensures thermal stability with a low temperature coefficient of 25ppm/°C
• Supports wide input voltage ranges for flexible power supply integration

Applications

• High-precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable voltage benchmarks
• Industrial process control instrumentation
• Test and measurement equipment calibration

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as REF01HPZ indicate RoHS compliance. Confirm the package type matches the target PCB footprint, specifically the 8-pin dual in-line configuration. Ensure the selected grade meets the required operational temperature range for the intended environment. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Selection Notes

Select this component when a fixed 10V reference is required with moderate precision and through-hole compatibility. Compare against REF01CN8#PBF or REF01EN8 if tighter accuracy or lower temperature coefficients are necessary. Evaluate the 1.4mA supply current against system power budgets. Consider the 8-PDIP package constraints for board layout and thermal management requirements.

Part Context

The REF01HP belongs to the REF01 family of precision voltage references from Analog Devices. This series includes variants offering different output voltages and accuracy grades. The HP variant specifically targets applications needing a robust 10V reference in a standard through-hole package, bridging the gap between general-purpose and ultra-high-precision requirements.

Replacement Considerations

REF01HPZ serves as a direct RoHS-compliant substitute within the same product line.
