MAX6071BAUT33+T

Overview

The MAX6071BAUT33+T is a low-noise, high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output of 3.3V with an initial accuracy of ±0.08% and a maximum temperature drift of 8ppm/°C. The device operates within an input voltage range of 3.5V to 5.5V and consumes a typical supply current of 240µA at +25°C. It supports bidirectional load currents up to 10mA and features a shutdown current of 6µA. The component is housed in a compact 6-pin SOT-23 package and is specified for operation across the extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Provides stable performance over temperature and time with high initial accuracy
• Features low noise characteristics suitable for precision applications
• Includes an enable pin for power management and shutdown control

Applications

• High-Accuracy Industrial and Process Control
• Precision Instrumentation
• High-Resolution ADCs and DACs
• Precision Current Sources

Procurement Notes

Verify the specific suffix 'B' indicates the ±0.08% accuracy grade and 'AUT' denotes the SOT-23-6 package configuration. Confirm that the '+T' suffix corresponds to tape-and-reel packaging as per the manufacturer's ordering guide. Ensure compatibility with the required input voltage range and thermal operating conditions before finalizing procurement.

Selection Notes

Select this component when a fixed 3.3V reference with ±0.08% accuracy is required. It is suitable for designs needing low quiescent current and bidirectional sourcing/sinking capabilities. Consider the MAX6070 variant if a filter option for wideband noise reduction is necessary instead of the standard MAX6071 architecture.

Part Context

This part belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. The family offers various output voltages and packages, including SOT-23 and WLP options. These devices are designed to enhance system accuracy in demanding environments through low drift and low noise specifications.

Replacement Considerations

MAX6070BAUT33+T is a functional substitute within the same family, differing primarily by the inclusion of a filter pin.
