MAX6078AMWT50+

Overview

The MAX6078AMWT50+T is a precision voltage reference from the MAX6078 family, manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 5.0V with an initial accuracy of ±0.04%. The device operates within an input supply range of 2.3V to 5.5V and supports a load current of up to 3mA for both sourcing and sinking. Key electrical characteristics include a maximum temperature drift of 10ppm/°C over the -55°C to +125°C industrial temperature range and a quiescent supply current of 15µA maximum. The component utilizes a 6-bump Wafer-Level Package (WLP) with dimensions of 1.5mm x 1.3mm.

Feature Summary

• Provides high-precision voltage regulation with low drift and low noise specifications suitable for demanding applications.
• Features independent force and sense outputs to cancel voltage drops on connecting lines, ensuring accurate load voltage.
• Includes a dedicated noise reduction pin allowing external capacitor connection to filter wideband noise.
• Offers an enable function that reduces supply current to less than 100nA during shutdown conditions.

Applications

• High-accuracy industrial and process control systems
• Precision instrumentation equipment
• High-resolution analog-to-digital and digital-to-analog converters
• Portable and handheld battery-powered systems

Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel configuration. Ensure the required output voltage matches the fixed 5.0V option designated by the model code. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component when system design requires minimal board space due to its compact WLP footprint. Consider the 5.0V output option if the application demands a standard logic-compatible reference level. Evaluate the need for the noise reduction feature based on the sensitivity of downstream ADC or DAC stages to high-frequency interference.

Part Context

This part belongs to the MAX6078A/MAX6078B family of low-power, low-drift voltage references. The 'A' designation indicates availability in multiple output voltage options excluding 1.25V, while the 'B' variant is restricted to the 1.25V output. The family is designed for applications requiring enhanced system accuracy through superior thermal stability and low power consumption profiles.

Replacement Considerations

Direct substitutes within the same family include MAX6078AMWT50+ without the tape-and-reel suffix, or other voltage variants such as MAX6078AMWT33+T for 3.3V requirements. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
