MAX6043AAUT41

Overview

The MAX6043AAUT41 is a precision series voltage reference from Analog Devices/Maxim Integrated, providing a fixed 4.096V output in a compact SOT-23-6 package. It features an initial accuracy of ±0.05% and a maximum temperature coefficient of 15ppm/°C. The device operates with an input voltage range of +4.5V to +40V and supports a maximum load current of 10mA. It draws a typical supply current of 650µA and exhibits low noise characteristics. The component functions reliably across an industrial temperature range of -40°C to +125°C.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high stability
• Capable of driving capacitive loads up to 100µF without requiring external stabilization capacitors
• Includes integrated short-circuit protection for enhanced operational safety

Applications

• High-resolution analog-to-digital converters (ADCs)
• Precision digital-to-analog converters (DACs)
• Digital voltmeters
• Threshold detectors

Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different tolerance grades or packaging options. Confirm current availability status through authorized distributors, as older Maxim products may have limited stock or end-of-life implications. Ensure the selected variant matches the required output voltage and accuracy specifications for the target application design.

Selection Notes

Select this component when a stable 4.096V reference is needed in a small footprint. The wide input voltage range allows flexibility in power supply design. Consider the ±0.05% accuracy and 15ppm/°C drift for applications demanding high precision. Verify that the 10mA output current meets the load requirements and that the SOT-23-6 thermal performance is sufficient for the operating environment.

Part Context

The MAX6043 series represents a line of high-precision voltage references designed for demanding analog signal processing tasks. Manufactured by Analog Devices/Maxim Integrated, these devices combine BICMOS technology with advanced trimming techniques. The family offers multiple preset voltages, catering to various industry standards while maintaining consistent performance metrics across the product line.

Replacement Considerations
