MAX6043BAUT25#TG16

Overview

The MAX6043BAUT25#TG16 is a precision high-voltage series voltage reference manufactured by Analog Devices Inc. (Maxim Integrated). It provides a fixed output voltage of 2.5V with an initial accuracy of 0.1% and a maximum temperature coefficient of 20ppm/°C. The device operates from a supply voltage range of 4.5V to 40V and supports a maximum shunt current of 10mA. It features low noise characteristics, including 9.5µVp-p (0.1Hz to 10Hz) and 15µVrms (10Hz to 10kHz), while consuming 650µA of supply current. The component is housed in a compact SOT-23-6 package and functions reliably within an operating temperature range of -40°C to +125°C.

Feature Summary

• Delivers precise fixed output voltages with tight initial accuracy and low temperature drift for stable reference performance.
• Operates directly from high input voltages up to 40V without requiring external step-down circuitry.
• Maintains stability with capacitive loads ranging from 0 to 100µF without the need for external compensation components.

Applications

• High-resolution analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• Precision sensor signal conditioning circuits

Procurement Notes

Verify the specific suffix #TG16 against official manufacturer documentation to confirm tape-and-reel packaging and RoHS compliance status. Confirm availability as some variants may be discontinued or subject to allocation. Ensure the ordering part number matches the required output voltage and accuracy grade exactly.

Selection Notes

Select this component when a stable 2.5V reference is required from high-voltage rails in space-constrained designs. The SOT-23-6 package offers a small footprint suitable for portable electronics. Consider the 20ppm/°C temperature coefficient and 0.1% initial accuracy against application requirements for precision instrumentation.

Part Context

This part belongs to the MAX6043 family of precision voltage references designed for high-voltage applications. The family includes various output voltage options such as 3.3V, 4.096V, 5.0V, and 10V. The BAUT25 designation specifically indicates the 2.5V output variant with 0.1% accuracy, distinguishing it from higher precision AA grades.

Replacement Considerations

Direct substitutes include other MAX6043 variants with different output voltages if system design allows adjustment. Cross-reference with MAX6043AAUT25 for tighter accuracy specifications. Verify pinout compatibility and thermal performance before substituting with generic voltage references.
