MAX6072AAUB25+

Overview

The MAX6072AAUB25+ is a dual-output precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides two fixed output voltages: VREF at 2.5V and VREF/2 at 1.25V. The device features an initial accuracy of 0.04% and a maximum temperature coefficient of 6ppm/°C over the -40°C to +125°C operating range. Each output can source and sink up to 10mA with independent sense lines for Kelvin connections. It operates within an input voltage range of 2.8V to 5.5V, consuming a typical quiescent current of 150µA per reference.

Feature Summary

• Dual outputs provide VREF and VREF/2 simultaneously for ADC/DAC referencing
• Independent force and sense lines enable precise Kelvin connection compensation
• Low thermal hysteresis ensures consistent results through temperature cycles
• Separate enable controls allow independent management of each output

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 'AAUB25+' corresponds to the 2.5V/1.25V output configuration and A-grade performance specifications. Confirm RoHS compliance status indicated by the '+' suffix. Ensure the package type matches the required 10-pin μMAX footprint for PCB layout compatibility.

Selection Notes

Select this component when a signal chain requires both a primary reference voltage and a precise half-voltage common-mode bias. The integrated dual-output design reduces board space compared to using separate discrete references. Verify that the 10mA output current capability meets the load requirements for both the reference and the downstream circuitry.

Part Context

This part belongs to the MAX6072 family of high-precision dual-output series voltage references. Other variants in the series include different output voltage pairs such as 5V/2.5V and 4.096V/2.048V, as well as B-grade options with slightly relaxed temperature coefficients. All variants share the same 10-pin μMAX package and core architecture.

Replacement Considerations

Direct substitutes within the same family include MAX6072BAUB25+ (B-grade) or other voltage variants like MAX6072AAUB41+ and MAX6072AAUB50+. Cross-family replacements require matching dual-output topology, package size, and electrical specifications.
