MAX6072AAUB41+T

Overview

The MAX6072AAUB41+T is a dual-output series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides two independent, fixed output voltages of 4.096V and 2.048V within a single package. The device operates with an input voltage range of 3.5V to 5.5V and draws a supply current of 330µA. It features a low noise profile of 6µVrms from 10Hz to 10Hz and maintains an initial accuracy of ±0.04%. The temperature coefficient is specified at 6ppm/°C, ensuring stability across the industrial operating temperature range of -40°C to +125°C. The component is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• High precision performance with ±0.04% initial accuracy and 6ppm/°C temperature coefficient
• Low noise operation delivering 6µVrms in the 10Hz to 10Hz frequency band
• Automotive-grade qualification compliant with AEC-Q100 standards

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable dual-rail references
• Industrial process control instrumentation
• Medical equipment signal conditioning circuits

Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or discontinuation. Confirm the specific suffix matches the required output voltages and package type. Check for RoHS compliance documentation and ensure the supplier provides valid traceability records. Due to potential obsolescence, validate lead times and substitute options before finalizing procurement plans.

Selection Notes

Select this component when dual isolated reference voltages are needed in a small footprint. The SOT-23-6 package offers space efficiency for dense PCB layouts. Ensure the input voltage remains within the 3.5V to 5.5V operational window. Consider the 330µA quiescent current for power-sensitive designs. Verify thermal management requirements for the +125°C maximum junction temperature limit.

Part Context

This device belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. It extends the family capabilities by integrating two distinct output voltages into one unit. The series is designed for applications demanding high accuracy and long-term stability. The MAX6072 variant specifically addresses designs requiring both 4.096V and 2.048V rails without using multiple discrete components.
