MAX6043BAUT41+T

Overview

The MAX6043BAUT41+T is a precision high-voltage series voltage reference manufactured by Analog Devices Inc. (Maxim Integrated). It provides a fixed output voltage of 4.096V and operates within an input supply range of +4.5V to +40V. The device features a maximum initial accuracy of 0.1% and a maximum temperature coefficient of 20ppm/°C. It supports a maximum shunt current of 10mA and functions across an extended operating temperature range from -40°C to +125°C. The component is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Provides precise, laser-trimmed fixed output voltages with tight initial accuracy specifications.
• Incorporates proprietary curvature-correction circuitry for low temperature drift stability.
• Operates directly from high-voltage inputs up to 40V without external regulation.
• Capable of driving capacitive loads up to 100µF without requiring external stabilization components.

Applications

• High-resolution analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage standards
• Precision sensor signal conditioning circuits
• Battery-powered instrumentation systems

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact electrical tolerances and thermal ratings. Confirm RoHS compliance status and environmental certifications prior to integration. Ensure the selected variant matches the required output voltage and accuracy grade for the target application design.

Selection Notes

Select this component when a stable, high-voltage tolerant reference is required in a minimal footprint. The SOT-23-6 package suits space-constrained designs. Evaluate the 20ppm/°C drift against system requirements. Consider the 10mA drive capability for load demands. Verify compatibility with downstream ADC/DAC input ranges.

Part Context

This part belongs to the MAX6043 family of precision voltage references designed for demanding industrial applications. The series offers multiple fixed output options including 2.5V, 3.3V, 4.096V, 5.0V, and 10V. The BA designation indicates specific accuracy and temperature coefficient grades within the product line, distinguishing it from other variants like the AA or AB series.

Replacement Considerations

Direct substitutes include other MAX6043 variants such as MAX6043AAUT41 or MAX6043BAUT41-TG16. Cross-reference pinouts and electrical parameters carefully. Verify that alternative packages maintain the same thermal and mechanical constraints for the existing PCB layout.
