MAX6021BEUR

Overview

The MAX6021BEUR is a precision, low-dropout, micropower voltage reference available in the miniature SOT-23-3 surface-mount package. It features a proprietary curvature-correction circuit and laser-trimmed thin-film resistors that result in a low temperature coefficient of less than 15ppm/°C and initial accuracy of better than 0.2%. The device operates over an extended temperature range.

Feature Summary

• Proprietary curvature-correction circuit for enhanced stability
• Laser-trimmed thin-film resistors ensure high precision
• Low temperature coefficient performance
• Extended temperature range operation

Applications

• Portable instrumentation
• Battery-powered systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm exact output voltage and tolerance grades. Confirm RoHS compliance status as manufacturing processes evolve. Ensure the ordering part number matches the required package type and temperature rating before procurement.

Selection Notes

Select this component when space constraints require a compact SOT-23-3 footprint alongside high precision requirements. Consider the micropower consumption profile for battery-operated designs. Verify that the input voltage range supports the system supply rails while maintaining low dropout characteristics.

Part Context

This component belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision voltage references. These devices share common architectural features such as curvature correction and laser trimming, offering consistent performance across various fixed output voltages within the series.

Replacement Considerations

Check for direct replacements within the same MAX60xx series with different output voltages or tolerances. Verify pin compatibility if substituting with other SOT-23-3 voltage references from Analog Devices.
