MAX6043BAUT10+T

Overview

The MAX6043BAUT10+T is a precision high-voltage series voltage reference manufactured by Analog Devices Inc. (Maxim Integrated). It provides a fixed output voltage of 10V with an initial accuracy of 0.1% and a maximum temperature coefficient of 25ppm/°C. The device operates from a supply voltage range of 4.5V to 40V and delivers up to 10mA of output current. It features low noise characteristics, including 9.5µVp-p (0.1Hz to 10Hz) and 15µVrms (10Hz to 10kHz), and is housed in a compact SOT-23-6 package suitable for surface mount applications.

Feature Summary

• Provides stable 10V reference output with tight initial accuracy
• Operates across a wide input voltage range up to 40V
• Features low noise performance suitable for high-resolution data converters
• Capable of sourcing 10mA load current without external stabilization capacitors

Applications

• High-resolution analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• Precision sensor signal conditioning circuits
• Battery-powered instrumentation requiring stable bias voltages

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when ordering. Confirm that the 'BAUT' designation corresponds to the 0.1% accuracy grade and 25ppm/°C temperature coefficient variant. Ensure compatibility with the 4.5V to 40V input range for your specific power supply design. Check for any recent product change notices or end-of-life announcements from the manufacturer regarding this specific part number revision.

Selection Notes

Select this component when a fixed 10V precision reference is required within a small SOT-23-6 footprint. It is appropriate for designs needing high input voltage tolerance up to 40V while maintaining low noise levels. Consider the 0.1% initial accuracy and 25ppm/°C drift if strict long-term stability is not the primary constraint compared to higher-grade variants like the AAUT series.

Part Context

The MAX6043BAUT10+T belongs to the MAX6043 family of precision voltage references. This family offers multiple fixed output voltages including 2.5V, 3.3V, 4.096V, 5.0V, and 10V. The BAUT suffix typically denotes the 0.1% accuracy class, distinguishing it from the higher-precision AAUT series which offers 0.05% accuracy. All variants share the same compact SOT-23-6 package and general electrical architecture.

Replacement Considerations

The MAX6043AAUT10+T is a verified substitute offering higher precision (0.05% accuracy, lower tempco) in the same package. Other MAX6043 variants with different output voltages may be used if the circuit design allows for voltage adjustment.
