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 from 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 within a temperature range of -40°C to +125°C. Packaged in a compact SOT-23-6 surface-mount format, it is designed for applications requiring stable reference voltages under varying thermal conditions.

Feature Summary

• Proprietary curvature-correction circuitry ensures low temperature drift and high stability across the operating range.
• Laser-trimmed thin-film resistors provide tight initial accuracy without requiring external trimming components.
• Capable of driving capacitive loads up to 100µF while maintaining stability without additional external capacitors.

Applications

• High-resolution analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• Precision sensor signal conditioning circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm that the 'BA' designation corresponds to the 0.1% accuracy grade and 20ppm/°C temperature coefficient specifications required for your design. Ensure the 4.096V output variant matches the system requirements before procurement.

Selection Notes

Select this component when a fixed 4.096V reference is needed with high precision in a small footprint. It is suitable for designs where the input voltage exceeds the reference output significantly, allowing operation up to 40V. Consider the 10mA load capability and the absence of shutdown functionality during the selection process.

Part Context

This part belongs to the MAX6043 family of precision voltage references. The family offers various fixed output voltages including 2.5V, 3.3V, 5.0V, and 10V. The MAX6043BAUT41-T specifically denotes the 4.096V output version with B-grade accuracy specifications.

Replacement Considerations

Direct substitutes within the same package and specification include MAX6043AAUT41-T or MAX6043CAUT41-T, noting differences in accuracy grades. Other MAX6043 variants with different output voltages are pin-compatible but require circuit adjustment.
