MAX6043CAUT10

Overview

The MAX6043CAUT10 is a precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated, housed in a compact SOT-23-6 surface-mount package. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.5%. The device operates within a wide input voltage range of 12V to 40V and supports a maximum shunt current of 10mA. Designed for industrial environments, it functions reliably across a temperature range from -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 components
• Includes integrated short-circuit protection to safeguard the device under fault conditions

Applications

• High-resolution analog-to-digital converter (ADC) systems
• Precision digital voltage measurement instruments
• Industrial control system signal conditioning

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices prior to procurement. Ensure packaging specifications match design requirements. Validate that the specific suffix corresponds to the desired accuracy grade and output voltage variant.

Selection Notes

Select this component when a stable 10V reference is required in space-constrained designs. The SOT-23-6 package offers a small footprint suitable for dense PCB layouts. Consider the ±0.5% initial accuracy and 15ppm/°C temperature coefficient for applications demanding moderate precision over a wide industrial temperature range.

Part Context

This part belongs to the MAX6043 family of high-voltage precision references. The series integrates BICMOS technology to deliver low noise and drift characteristics. Other variants in the lineup offer different fixed output voltages such as 2.5V, 3.3V, 4.096V, and 5.0V, catering to diverse reference needs while maintaining similar package and protection features.

Replacement Considerations

Direct substitutes include other MAX6043 variants with identical pinouts but different output voltages or accuracy grades, such as MAX6043BAUT10 or MAX6043AAUT10. Verify that any replacement maintains the required 10V output and meets the specific accuracy and temperature coefficient constraints of the original design.
