ADR01BRZ

Overview

The ADR01BRZ is a precision series voltage reference IC manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.05%. The device operates within an input voltage range of 12V to 36V and draws a supply current of 1mA. It delivers a maximum output current of 10mA and exhibits a temperature coefficient of 3ppm/°C. Low-frequency noise is specified at 20µVp-p from 0.1Hz to 10Hz, ensuring stable performance across the industrial temperature range of -40°C to +125°C.

Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Features low temperature coefficient for stable performance across wide thermal ranges
• Delivers sufficient drive capability for standard analog signal conditioning loads

Applications

• Precision digital-to-analog conversion systems
• High-resolution data acquisition circuits
• Calibration equipment requiring stable reference sources

Procurement Notes

Verify the specific suffix BRZ indicates the RoHS-compliant 8-SOIC package variant when sourcing. Confirm that the 10V output version matches system requirements, as other variants in the ADR01 family offer different fixed voltages. Ensure input voltage constraints between 12V and 36V are respected during design integration to maintain regulation and prevent damage.

Selection Notes

Select this component when a 10V reference is required with ±0.05% initial accuracy and low drift characteristics. Compare against the ADR01ARZ if higher temperature stability is not critical but cost reduction is needed, noting the difference in temperature coefficients. Ensure the 10mA output current meets load demands without exceeding thermal limits in the SOIC package.

Part Context

This part belongs to the ADR01/ADR02/ADR03/ADR06 family of precision bandgap voltage references designed for general-purpose high-accuracy applications. Unlike the XFET technology found in the ADR4xx series, these devices utilize bandgap architecture optimized for low power consumption and compact packaging while maintaining industry-standard pinouts for easy replacement.

Replacement Considerations

The ADR01ARZ serves as a direct functional substitute with identical electrical parameters except for a looser temperature coefficient specification. Verify package compatibility and output voltage matching before substitution.
