MAX6067AEUR+T

Overview

The MAX6067AEUR+T is a precision, micropower voltage reference from the MAX6061–MAX6068 series. It provides a fixed output voltage of 4.5V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 20ppm/°C. The device operates within an extended temperature range of -40°C to +85°C and features a typical quiescent supply current of 90µA. It supports sourcing up to 5mA and sinking up to 2mA of load current while maintaining stability without requiring external compensation capacitors.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high precision and low temperature drift.
• Series-mode architecture eliminates the need for external biasing resistors, offering supply current virtually independent of input voltage variations.
• Internally compensated design removes the requirement for external frequency-stabilization capacitors, reducing board space consumption.
• Low dropout voltage and ultra-low power consumption make the component suitable for battery-operated systems.

Applications

• Analog-to-Digital Converters (ADCs)
• Portable Battery-Powered Systems
• Precision 3V/5V Systems

Procurement Notes

Verify the specific suffix 'EUR' corresponds to the SOT-23-3 package configuration required for your layout. Confirm that the '+T' designation aligns with your preferred reel or cut-tape packaging format. Ensure the manufacturer is identified as Analog Devices Inc. or Maxim Integrated to guarantee authenticity. Cross-reference the top marking 'FZFS' against official documentation to validate the part during incoming inspection.

Selection Notes

Select this component when a stable 4.5V reference is required in space-constrained designs. The ±0.2% accuracy class is appropriate for applications demanding tight tolerance without the complexity of adjustable references. Consider the 90µA quiescent current for battery life calculations. Verify that the input voltage remains above the minimum dropout threshold relative to the 4.5V output under all operating conditions.

Part Context

This part belongs to the MAX6061–MAX6068 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common architectural features including micropower operation and SOT-23 packaging. Variations within the series are defined primarily by their fixed output voltage options, ranging from 1.25V to 5V, while maintaining similar performance characteristics regarding noise and stability.

Replacement Considerations
