MAX6009AEUR-T

Overview

The MAX6009AEUR-T is a precision shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It operates within an input voltage range of 2.7V to 12.6V and delivers a fixed output voltage of 3V with an initial accuracy of 0.5%. The device features a temperature coefficient of 75 PPM/°C and supports a maximum shunt current of 2 mA. Designed for surface-mount installation, it is housed in a compact SOT-23-3 package. The component functions reliably across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides stable 3V reference via shunt topology
• Ensures high precision with 0.5% initial accuracy
• Operates efficiently on low supply voltages down to 2.7V

Applications

• Portable instrumentation requiring precise voltage standards
• Battery-powered measurement systems
• Data acquisition channels needing stable references

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the exact electrical specifications required for the design. Cross-reference the manufacturer's latest datasheet for any potential lifecycle changes or pinout updates before finalizing procurement plans.

Selection Notes

Select this component when a fixed 3V reference is required in space-constrained designs utilizing the SOT-23-3 footprint. It is suitable for applications where moderate accuracy (0.5%) and standard noise performance are sufficient. Consider the 75 PPM/°C temperature coefficient against environmental operating conditions. Verify that the system can accommodate the shunt configuration requirements and maximum current limits specified in the datasheet.

Part Context

This part belongs to the MAX6009 series of micropower voltage references designed for battery-operated equipment. The series offers various output voltages and accuracy grades to suit different application needs. As a shunt reference, it regulates voltage by sinking current to ground, making it distinct from series regulators. The Maxim Integrated brand heritage ensures compatibility with established power management design practices.

Replacement Considerations

Consult the manufacturer's cross-reference guide for direct replacements. Verify that alternative parts match the 3V output, SOT-23-3 package, and 0.5% accuracy constraints. Ensure thermal and electrical characteristics align with the original design requirements.
