REF01HZ

Overview

The REF01HZ is a precision series voltage reference IC manufactured by Analog Devices Inc., providing a fixed 10 V output. It features an initial accuracy of ±0.5% and a temperature coefficient of 25 ppm/°C. The device operates within an input voltage range of 13 V to 33 V and supports a maximum output current of 10 mA. It is housed in an 8-CERDIP package and functions at temperatures between -40°C and +85°C.

Feature Summary

• Provides a stable 10 V reference output with high initial accuracy
• Offers adjustable output capability over a 3% range
• Maintains excellent temperature stability across the operating range

Applications

• Precision analog interface circuits
• Data acquisition systems requiring stable references
• Instrumentation amplifier biasing

Procurement Notes

Verify the specific suffix requirements for your application, as package variations exist within the REF01 family. Confirm that the 8-CERDIP package aligns with your PCB layout constraints. Ensure the 10 mA output current meets your load requirements. Check for RoHS compliance status if required by your manufacturing standards. Validate the operating temperature range against your environmental conditions.

Selection Notes

Select this component when a fixed 10 V reference is required with moderate accuracy. Consider the 8-CERDIP package for through-hole mounting needs. Evaluate the 25 ppm/°C drift against stricter low-drift alternatives like the REF01EN8 if higher precision is necessary. Ensure the input voltage stays within the 13 V to 33 V range for proper regulation.

Part Context

The REF01HZ belongs to the REF01 series of precision voltage references from Analog Devices. This series is designed for applications demanding stable voltage sources. The part shares core functionality with other REF01 variants but differs in package type and specific performance metrics such as accuracy and temperature coefficient.

Replacement Considerations

Direct substitutes include REF01HPZ and REF01CN8#PBF. Verify pin compatibility and electrical specifications before substitution.
