MAX6064BEUR

Overview

The MAX6064BEUR is a precision, micropower, low-dropout voltage reference from the Maxim Integrated family. It provides a fixed output of 4.096 V with an initial accuracy of ±0.4% and a temperature coefficient of 6 ppm/°C. The device operates within an input voltage range up to 13.5 V and supports a maximum shunt current of 5 mA. It functions reliably across an extended temperature range from -40°C to +85°C. Typical supply current is 90 µA, with a maximum of 125 µA. Packaged in a compact SOT-23-3 surface-mount case, it is designed for space-constrained applications requiring stable voltage regulation.

Feature Summary

• Utilizes proprietary curvature correction circuitry and laser-trimmed thin-film resistors for high stability
• Features low dropout operation suitable for battery-powered systems
• Delivers high output current capability relative to its power consumption

Applications

• Portable instrumentation requiring precise voltage standards
• Battery-operated measurement devices
• Data acquisition systems needing stable reference sources

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and specific suffix designations against official datasheets. Check for obsolescence notices as availability may vary by region. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this part when a fixed 4.096 V reference is required with tight tolerance specifications. Consider the SOT-23-3 package for board space limitations. Evaluate thermal performance within the -40°C to +85°C operating range. Compare power consumption against system budget constraints given the micropower characteristics.

Part Context

This component belongs to the MAX606x series of voltage references manufactured by Analog Devices Inc./Maxim Integrated. The series includes various output voltages and accuracy grades. The MAX6064 variant specifically targets applications needing 4.096 V precision. It shares architectural similarities with other members like the MAX6065 and MAX6066 but differs in output settings and specific trim parameters.

Replacement Considerations

Direct substitutes include MAX6064BEUR+T and MAX6064BEUR-T. Verify pin compatibility and electrical specifications before substitution. Cross-reference with MAX6065BEUR or MAX6066BEUR only if output voltage differences are acceptable.
