MAX6037BAUK41

Overview

The MAX6037BAUK41 is a series voltage reference IC from the MAX6037 family, manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096V with an initial accuracy of ±0.3%. The device operates within an input voltage range of 4.3V to 5.5V and supports a maximum shunt current of 5 mA. It is housed in a SOT-23-5 package and features a temperature coefficient of 50 ppm/°C. Noise performance is specified at 24 µVp-p (0.1Hz to 10Hz) and 50 µVrms (10Hz to 10kHz).

Feature Summary

• Low-dropout micropower architecture for energy-efficient operation.
• Fixed precision output voltage option within the adjustable family range.
• Compact SOT-23-5 surface-mount packaging.

Applications

• Precision analog-to-digital converter (ADC) references.
• Data acquisition systems requiring stable voltage sources.
• Battery-powered instrumentation.

Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as some listings indicate non-compliance. Ensure the supplier source matches the manufacturer's authorized distribution channels to guarantee authenticity. Check lead times as availability may vary by region.

Selection Notes

Select this part for applications requiring a fixed 4.096V reference with moderate precision. Compare against the MAX6037B family for adjustable options if wider voltage ranges are needed. Consider the 50 ppm/°C temperature coefficient for thermal stability requirements. Verify input voltage compatibility within the 4.3V to 5.5V range.

Part Context

The MAX6037BAUK41 belongs to the MAX6037 family of low-power voltage references. This family offers both fixed and adjustable output voltages ranging from 1.184V to 5V. The BAUK41 variant specifically provides the 4.096V fixed output option, distinguishing it from other variants like the UK33 (3.3V) or adjustable models.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The MAX6043BAUT25+T is listed as a comparison but has different specifications (SOT-23-6, 0.1% accuracy). Verify pinout and electrical parameters before substituting with any other component.
