MAX6012BEUR

Overview

The MAX6012BEUR is a buried Zener precision voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 1.247V with an initial accuracy of ±0.48%. The device features a maximum temperature coefficient of 3ppm/°C and operates within an input voltage range up to 5.5V. It draws a maximum supply current of 500µA and functions reliably across a temperature range of -40°C to +85°C. The component is housed in a compact SOT-23-3 surface-mount package, designed for high-precision applications requiring low drift.

Feature Summary

• Utilizes buried Zener technology for ultra-low drift performance
• Provides fixed 1.247V output with high initial accuracy
• Features extremely low temperature coefficient for thermal stability

Applications

• Precision digital-to-analog converter (DAC) systems
• High-resolution analog-to-digital converter (ADC) references
• Instrumentation requiring stable voltage baselines

Procurement Notes

Verify the specific suffix of the part number when ordering, as variants such as MAX6012BEUR+T may have different availability or packaging configurations compared to the base MAX6012BEUR. Confirm that the source document explicitly supports the requested variant's specifications. Cross-reference the manufacturer's latest datasheet to ensure compliance with current RoHS standards and environmental regulations before finalizing procurement decisions.

Selection Notes

Select this component when application requirements demand minimal voltage drift over temperature changes. The buried Zener architecture offers superior long-term stability compared to standard bandgap references. Ensure the system input voltage remains within the specified maximum limit. Consider the SOT-23-3 package constraints regarding thermal dissipation and physical space limitations in dense PCB layouts.

Part Context

This component belongs to the MAX601x series of precision voltage references from Maxim Integrated. It shares design principles with other members like the MAX6009 and MAX6010 but distinguishes itself through its specific 1.247V output and buried Zener construction. The series targets applications where precision and low noise are critical, serving as a foundational reference element in mixed-signal circuits.

Replacement Considerations
