MAX6037BAUK21

Overview

The MAX6037BAUK21 is a low-power, fixed-output voltage reference from the Maxim Integrated portfolio, now part of Analog Devices. It provides a precise 2.048 V output with an initial accuracy of 0.2% and a temperature coefficient of 6 PPM/°C. The device operates within an input voltage range up to 6 V and supports a maximum shunt current of 5 mA. It functions reliably across an extended industrial temperature range from -40°C to +125°C. Packaged in a compact SOT-23-5 surface-mount format, it is designed for applications requiring stable reference voltages in space-constrained environments.

Feature Summary

• Provides a fixed 2.048 V output with high initial accuracy
• Features low temperature drift for stable performance over wide thermal ranges
• Supports shutdown functionality for power conservation
• Utilizes a compact SOT-23-5 package for space-efficient designs

Applications

• Portable instrumentation systems requiring precise voltage references
• Battery-powered measurement devices needing low quiescent current
• Data acquisition systems utilizing analog-to-digital converters
• Industrial process control loops with strict accuracy requirements

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or official ADI channels. Confirm the specific suffix indicates the correct output voltage and package variant. Check for recent product change notices or lifecycle status updates on the ADI website. Ensure compliance with RoHS directives if required by your manufacturing standards. Validate that the sourcing partner maintains proper chain-of-custody documentation.

Selection Notes

Select this component when a stable 2.048 V reference is needed with minimal temperature drift. Consider the 0.2% initial accuracy for precision applications. Evaluate the SOT-23-5 footprint against available board space constraints. Compare power consumption requirements against the device's low quiescent current specifications. Ensure the operating temperature range aligns with your system's environmental conditions.

Part Context

This part belongs to the MAX6037 series of low-power voltage references. The 'B' suffix typically denotes a specific accuracy grade, while 'UK' indicates the SOT-23-5 package type. The '21' suffix specifies the 2.048 V output voltage. This series is designed for portable and battery-operated equipment where power efficiency and size are critical design factors.

Replacement Considerations

Consult the official Analog Devices replacement guide for verified cross-references. Verify pinout compatibility before substituting with other MAX6037 variants. Ensure the alternative part matches the required output voltage and accuracy grade. Check for any functional differences in shutdown mechanisms or load regulation characteristics.
