MAX6043CAUT41

Overview

The MAX6043CAUT41 is a precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096 V with an initial accuracy of 0.05% and a maximum temperature coefficient of 15 ppm/°C. The device operates from a wide supply voltage range of 4.5 V to 40 V and supports a maximum load current of 10 mA. It functions within an industrial temperature range of -40°C to +125°C and is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Features proprietary curvature-correction circuitry for low temperature drift
• Capable of driving capacitive loads up to 100µF without external compensation
• Includes short-circuit protection for enhanced reliability

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 'AUT41' against official manufacturer documentation to confirm the exact output voltage and tolerance grade. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the ordering part number matches the required electrical specifications before procurement.

Selection Notes

Select this component when a stable 4.096 V reference is required from high-voltage inputs up to 40 V. It is suitable for applications demanding tight initial accuracy and low noise in space-constrained designs. Consider the SOT-23-6 package size and thermal characteristics relative to the PCB layout requirements.

Part Context

This part belongs to the MAX6043 family of precision voltage references designed for high-performance data acquisition systems. The series offers multiple fixed output voltages including 2.5 V, 3.3 V, 5.0 V, and 10 V variants. These devices are engineered to replace bulkier traditional references while maintaining superior stability and accuracy in portable and industrial equipment.

Replacement Considerations

Direct substitutes include other MAX6043 variants with different output voltages or tolerances, such as MAX6043AAUT25 or MAX6043BAUT33. Verify pinout compatibility and electrical parameter alignment before substitution.
