REF01HPZ

Overview

The REF01HPZ is a precision series voltage reference integrated circuit manufactured by Analog Devices Inc. It provides a fixed output voltage of 10 V with an initial accuracy tolerance of ±0.5%. The device operates within an extended industrial temperature range of -40°C to +85°C and features a low temperature coefficient of 25 ppm/°C. Designed for through-hole mounting, it utilizes an 8-PDIP package. Key electrical specifications include a maximum input voltage range of 13 V to 33 V, a supply current of 1.4 mA, and a maximum output current of 10 mA. Low-frequency noise performance is specified at 30 µVp-p from 0.1 Hz to 10 Hz.

Feature Summary

• Delivers stable 10 V reference output with high initial accuracy
• Operates reliably across extended industrial temperature ranges
• Features low temperature coefficient for thermal stability
• Designed for through-hole integration in compact packages

Applications

• High-resolution analog-to-digital converter (ADC) reference sources
• Precision data acquisition systems requiring stable voltage rails
• Industrial process control instrumentation
• Medical ultrasound equipment signal conditioning

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to ensure correct accuracy grade and temperature rating. Confirm RoHS compliance status and packaging type requirements prior to ordering. Check for recent product change notifications regarding redesigns or manufacturing site transfers. Ensure compatibility with existing board layouts for 8-PDIP through-hole mounting.

Selection Notes

Select this component when a fixed 10 V reference is required with moderate precision and extended temperature capability. Compare against lower accuracy variants like REF01CPZ if cost is critical, or higher precision models like REF01EN8 if tighter tolerances are needed. Evaluate power consumption constraints given the 1.4 mA supply current. Ensure input voltage stays within the 13 V to 33 V operational window.

Part Context

The REF01HPZ belongs to the REF01 family of precision voltage references from Analog Devices. This series includes various accuracy grades and output voltages. The HPZ variant specifically denotes the 10 V output with ±0.5% accuracy and industrial temperature range. It serves as a foundational component for analog signal chain design where reference stability directly impacts system resolution.

Replacement Considerations
