MAX6043AAUT41#TG16

Overview

The MAX6043AAUT41#TG16 is a precision high-voltage series voltage reference manufactured by Analog Devices Inc. (Maxim Integrated). It provides a fixed +4.096V output voltage and operates from a wide supply voltage range of +4.5V to +40V. The device features an initial accuracy of ±0.05% maximum and a temperature coefficient of 15ppm/°C maximum. It is housed in a compact SOT-23-6 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Proprietary curvature-correction circuit for low temperature drift
• Laser-trimmed thin-film resistors ensure tight initial accuracy
• Capable of driving capacitive loads up to 100µF without external compensation

Applications

• High-resolution analog-to-digital converters
• Digital-to-analog converters
• Precision measurement instrumentation

Procurement Notes

Verify the specific suffix #TG16 against official manufacturer documentation, as this indicates tape-and-reel packaging. Confirm current availability status, as the MAX6043 family has been subject to discontinuance notices. Ensure the selected output voltage variant matches the design requirement before procurement.

Selection Notes

Select this component when a stable 4.096V reference is required within a small footprint. It is suitable for designs needing high input voltage tolerance up to 40V. Consider the ±0.05% accuracy and 15ppm/°C stability for applications demanding minimal calibration. Verify that the load capacitance does not exceed the specified limit for stability.

Part Context

This part belongs to the MAX6043 family of precision voltage references. The family offers multiple fixed output voltages including 2.5V, 3.3V, 4.096V, 5.0V, and 10V. All variants share similar electrical characteristics and package options, differing primarily in their preset output voltage levels.

Replacement Considerations

Check for direct substitutes within the MAX6043 family with different output voltages if the 4.096V specification is flexible. Verify pinout compatibility with any cross-brand alternatives.
