MAX6030BEUR

Overview

The MAX6030BEUR is a precision series voltage reference from the Maxim Integrated portfolio, housed in a compact SOT-23-3 surface-mount package. It delivers a fixed output of 3V with an initial accuracy of ±0.5%. The device operates within an input voltage range of 3.2V to 12.6V and draws a maximum supply current of 35µA. It maintains stability across a temperature range of -40°C to +85°C with a temperature coefficient of 75ppm/°C. Designed for low-power applications, it features a low-dropout architecture suitable for battery-powered systems requiring high precision.

Feature Summary

• Provides stable 3V reference output with ±0.5% initial accuracy
• Operates on ultra-low quiescent current of 35µA maximum
• Supports wide input voltage range up to 12.6V
• Compact SOT-23-3 footprint for space-constrained designs

Applications

• Portable instrumentation and handheld meters
• Battery-powered data acquisition systems
• Precision analog-to-digital converter (ADC) references
• Medical monitoring equipment requiring stable bias voltages

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm exact tolerance and temperature grade. The 'BEUR' designation indicates a specific binning or packaging configuration; ensure compatibility with your PCB footprint and thermal requirements. Cross-reference with authorized distributors to confirm current availability status, as lead times may vary based on production cycles.

Selection Notes

Select this component when system design demands a fixed 3V reference with moderate precision (±0.5%) in a minimal footprint. It is appropriate for applications where power consumption must be minimized without sacrificing significant accuracy. Compare against the MAX6030AEUR variant if tighter initial accuracy (±0.2%) is required, noting that the BEUR version offers a cost-effective solution for standard industrial specifications.

Part Context

The MAX6030 series represents Maxim Integrated's approach to combining precision voltage referencing with low power consumption in small packages. Part of the broader PMIC family, it serves as a critical building block for signal conditioning chains. The BEUR variant specifically targets applications needing reliable performance in consumer and industrial electronics where board real estate is limited.

Replacement Considerations

Direct substitutes include the MAX6030AEUR for higher accuracy needs or other series references from the same family. Verify pinout compatibility and thermal characteristics before substitution. Ensure any replacement maintains the required output voltage and current drive capabilities for the specific circuit load.
