MAX6129AEUK33-T

Overview

The MAX6129AEUK33-T is a series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 3.3 V with an initial accuracy of 0.4% and a temperature coefficient of 40 PPM/C. The device operates within an input voltage range up to 13 V and supports a maximum shunt current of 4 mA. It functions reliably across a temperature range from -40 C to +85 C. The component is housed in a SOT-23-5 surface-mount package.

Feature Summary

• Ultra-low-power series voltage reference design
• Fixed 3.3 V output capability
• High precision with 0.4% initial accuracy

Applications

• Portable instrumentation systems
• Battery-powered measurement devices
• Data acquisition circuits requiring stable references

Procurement Notes

Verify the exact suffix configuration against official documentation, as variations such as +T indicate specific packaging or compliance standards. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the ordering part number matches the required tolerance and package type specifications for your design.

Selection Notes

Select this component when a stable 3.3 V reference is needed with moderate precision requirements. The 0.4% accuracy and 40 PPM/C drift suit applications where ultra-high precision is not critical but low power consumption is essential. Compare against higher accuracy alternatives if tighter tolerances are required for your specific signal chain.

Part Context

This part belongs to the MAX6129A series of voltage references. It shares the SOT-23-5 footprint with other variants in the family but differs in output voltage and accuracy grades. It serves as a compact solution for space-constrained designs requiring a reliable voltage baseline without the complexity of adjustable references.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6129 series that offer different accuracy grades or output voltages. Verify thermal performance and current consumption limits against alternative components to ensure system compatibility.
