Overview
The MAX6072AAUB41+ is a dual-output precision series voltage reference in a 10-pin µMAX package. It provides VREF at 4.096V and VREF/2 at 2.048V with an initial accuracy of 0.05% and a maximum temperature coefficient of 6ppm/°C. Each output sources and sinks up to 10mA and features independent force and sense lines for Kelvin connection accuracy. The device operates within an input voltage range of 2.8V to 5.5V, consuming approximately 150µA per reference. It includes separate enable controls and exhibits low thermal hysteresis.
Feature Summary
- Dual outputs providing both full-scale reference voltage and half-scale common-mode bias
- Independent Kelvin force and sense connections on each output channel
- Separate enable inputs allow individual control of each reference output
- Low long-term drift ensures stable signal chain readings over time
Applications
- ADC/DAC references and common-mode set-point generation
- Test and measurement equipment and automated test systems
- High-accuracy industrial and process control applications
- Portable medical devices requiring precise analog front ends
Procurement Notes
Verify the specific suffix 'A' indicates A-grade performance with a 6ppm/°C temperature coefficient and 0.05% accuracy. Confirm the 'UB41' designation corresponds to the 4.096V/2.048V output pair. Ensure the '+T' suffix matches the required reel packaging format for your assembly line. Cross-reference the manufacturer part number against official distributor catalogs to confirm current availability status.
Selection Notes
Select this component when a single package must provide both a primary reference voltage and a precise half-voltage common-mode bias. The independent sense lines are critical for maintaining accuracy across PCB traces. Verify that the 10mA output current capability meets the load requirements for both the ADC reference and the differential amplifier input stages.
Part Context
This device belongs to the MAX6072 family of high-precision dual-output series voltage references. It shares the same 10-pin µMAX footprint and functional architecture as other variants in the series, differing primarily in output voltage pairs and grade specifications. The family is designed to simplify signal chain design by integrating two matched references into one compact package.
Replacement Considerations
Public confirmed substitute part numbers: MAX6072BAUB41+, MAX6072AAUB50+, MAX6072BAUB50+
FAQ
How does the MAX6072 handle trace resistance errors?
It utilizes independent Kelvin force and sense connections (OUTF and OUTS) for each output, allowing the device to regulate the voltage directly at the load and cancel out trace resistance drops.
Can the outputs be enabled independently?
Yes, the device features separate enable inputs (EN1 and EN2), allowing each reference output to be powered up or shut down individually to save power.
