MAX6072AAUB50+

Overview

The MAX6072AAUB50+ is a dual-output precision series voltage reference in a 10-pin µMAX package. It provides fixed outputs of 5V and 2.5V with an initial accuracy of ±0.05% and a maximum temperature coefficient of 6ppm/°C over the -40°C to +125°C range. Each output sources and sinks up to 10mA with independent force and sense lines. Quiescent current is typically 150µA per reference, and it features separate enable controls.

Feature Summary

• Dual Kelvin-connected outputs (Force/Sense) for high-precision regulation
• Independent enable inputs for each reference channel
• Low thermal hysteresis ensures consistent results through temperature cycles
• Excellent long-term drift stability for accurate signal chain readings

Applications

• ADC/DAC References and Common-Mode Set-Point
• Test and Measurement/ATE
• High-Accuracy Industrial and Process Control
• Portable Medical

Procurement Notes

Verify the specific suffix against official documentation to confirm RoHS compliance and package type. Ensure the ordering code matches the required voltage pair and grade specifications. Confirm availability status directly with authorized distributors as supply conditions may vary.

Selection Notes

Select this part when a single component must provide both a main reference voltage and a precise half-voltage common-mode bias. The integrated dual architecture reduces board space compared to using two discrete references. Verify that the input voltage headroom accommodates the dropout requirements at maximum load currents.

Part Context

This device belongs to the MAX6072 family of high-precision dual-output series voltage references. It is manufactured by Analog Devices Inc./Maxim Integrated. The family includes variants with different output voltages (5V/2.5V, 4.096V/2.048V, 2.5V/1.25V) and grades (A-grade and B-grade) offering varying temperature coefficients.

Replacement Considerations

Direct substitutes within the same family include MAX6072BAUB50+ (B-grade, 8ppm/°C). Other voltage pairs like MAX6072AAUB41+ or MAX6072AAUB25+ are functionally similar but provide different output levels.
