MAX6072AAUB50+T

Overview

The MAX6072AAUB50+T is a high-precision, dual-output series voltage reference manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides fixed output voltages of 2.048V and 4.096V with an initial accuracy of ±0.04%. The device operates within an input voltage range of 2.8V to 5.5V and draws a supply current of 320µA. It features low noise characteristics, specified at 10µVp-p from 0.1Hz to 10Hz and 6µVrms from 10Hz to 10kHz. The temperature coefficient is 6ppm/°C, and it supports a load current of 10mA per channel. The component is housed in a compact 10-uMAX/uSOP package and functions reliably across an operating temperature range of -40°C to +125°C.

Procurement Notes

Verify the specific suffix 'AAUB50' against official Analog Devices documentation to confirm the exact output voltage combination and accuracy grade. Confirm RoHS compliance status through the manufacturer's latest product change notices. Check for availability constraints as this component may be subject to limited stock or discontinuation notices. Ensure the 10-uMAX package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when dual, matched voltage references are required in a single package to save board space. The low noise and high accuracy make it suitable for applications where signal integrity is critical. Consider the 10mA output current capability to ensure it meets the load requirements of downstream circuitry. Evaluate the 2.8V minimum input voltage to ensure compatibility with the system power supply rail.

Part Context

This part belongs to the MAX6072 series of high-precision voltage references from Maxim Integrated. The series is designed for applications requiring stable, low-noise voltage sources. The AA suffix typically denotes a specific accuracy grade, while the UB indicates the 10-uMAX package type. The +T suffix signifies tape-and-reel packaging for automated assembly.

Replacement Considerations

Consult official Analog Devices cross-reference tools for verified substitutes. Potential alternatives include other dual-output series references from the same family with compatible pinouts and electrical specifications. Verify that any replacement matches the 10-uMAX package and maintains similar noise and accuracy levels.
