MAX6043AAUT41-T

Overview

The MAX6043AAUT41-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, derived from the standard +4.096V option within the MAX6043 family. The device operates from a wide supply voltage range of +4.5V to +40V and features an initial accuracy of 0.05% maximum. It exhibits a low temperature coefficient of 15ppm/°C maximum and low noise characteristics, making it suitable for high-resolution data converter applications. The component is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Provides precise fixed reference voltage with tight initial accuracy
• Operates from high input voltages up to 40V
• Features low temperature drift for stable performance across wide thermal ranges
• Capable of driving capacitive loads without external stabilization components

Applications

• High-resolution analog-to-digital converters (ADCs)
• Digital-to-analog converters (DACs)
• Precision measurement instrumentation
• Data acquisition systems requiring stable voltage references

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration as per manufacturer standards. Confirm the 'AA' grade corresponds to the 0.05% accuracy specification. Ensure the operating environment remains within the -40°C to +125°C temperature range. Check for end-of-life status or discontinuance notices from Analog Devices prior to final design approval.

Selection Notes

Select this part when a 4.096V reference is required with high accuracy and wide input voltage capability. The SOT-23-6 package suits space-constrained designs. Consider the 15ppm/°C temperature coefficient for thermal stability requirements. Verify that the load capacitance does not exceed the specified limits for stability without external components.

Part Context

The MAX6043 series belongs to Maxim Integrated's portfolio of precision voltage references designed for demanding industrial and communication applications. This specific variant offers the 4.096V output level, complementing other options like 2.5V, 3.3V, 5.0V, and 10V within the same family. The series utilizes laser-trimmed thin-film resistors and curvature-correction circuits to achieve superior performance.

Replacement Considerations

Direct substitutes include other MAX6043 variants with different output voltages if the voltage level can be adjusted or if a different reference is acceptable. Cross-reference with MAX6043AAUT41#TG16 for potential packaging or reel variations. Verify pinout compatibility and electrical specifications against alternative precision references from Analog Devices.
