MAX6043CAUT33-T

Overview

The MAX6043CAUT33-T is a precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 3.3V with an initial accuracy of 0.1% and a temperature coefficient of 15ppm/°C. The device operates from a wide supply voltage range of 4.5V to 40V and supports a maximum load current of 10mA. 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
• Laser-trimmed thin-film resistors ensure tight initial accuracy
• 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 standards
• Precision sensor signal conditioning circuits
• Portable instrumentation requiring stable voltage sources

Procurement Notes

Verify the specific suffix against official manufacturer documentation, as variations may indicate different accuracy grades or packaging options. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability for this component can fluctuate based on production cycles and regional stock levels.

Selection Notes

Select this component when a high-voltage input range up to 40V is required alongside precise 3.3V regulation. It is suitable for designs needing stability under varying capacitive loads without additional components. Consider the 15ppm/°C drift specification for applications demanding consistent performance across wide industrial temperature extremes.

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 2.5V, 4.096V, 5.0V, and 10V variants. These devices are engineered to replace bulkier traditional references while maintaining superior noise and drift characteristics in small form factors.

Replacement Considerations

Direct substitutes include other MAX6043 variants with different output voltages such as MAX6043AAUT25-T or MAX6043BAUT33-T. Ensure the replacement matches the required output voltage and accuracy grade. Verify that the pinout remains compatible with the existing SOT-23-6 footprint.
