MAX6071AAUT33+T

Overview

The MAX6071AAUT33+T is a low-noise, high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 3.3V with an initial accuracy of ±0.04% and a maximum temperature drift of 6ppm/°C (A grade). The device operates within an input voltage range of 3.5V to 5.5V and consumes a typical supply current of 160µA at +25°C. It supports sourcing and sinking up to 10mA of load current and features a shutdown supply current of 6µA. Packaged in a compact 6-pin SOT-23 format, it is specified for operation over the extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Provides stable performance over temperature and time with high initial accuracy and low temperature drift.
• Features very low noise characteristics suitable for precision applications.
• Includes an enable pin for power management and low quiescent current consumption.
• Capable of sourcing and sinking significant load currents while maintaining stability.

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 'A' grade designation corresponds to the required 6ppm/°C maximum temperature coefficient. Ensure the '+T' suffix aligns with RoHS compliance requirements for your assembly process. Cross-reference the full part number against official distributor catalogs to confirm availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a fixed 3.3V reference with high precision is required in a small footprint. The MAX6071 variant offers faster turn-on settling compared to the MAX6070, which lacks the filter option. Consider the 10mA output drive capability for direct interfacing with downstream circuitry. Verify that the 3.5V minimum input voltage requirement fits within your system's supply headroom constraints.

Part Context

This device belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. The MAX6071 distinguishes itself from the MAX6070 by omitting the internal filter option, resulting in significantly faster transient response times. Both devices share similar electrical characteristics regarding noise, accuracy, and package options, catering to diverse precision analog design needs.

Replacement Considerations

The MAX6070AAUT33+T serves as a functional substitute within the same family, differing primarily in the absence of the filter pin and associated transient response characteristics. Other MAX6071 variants with different output voltages or grades may be considered if voltage levels or drift specifications require adjustment.

FAQ

What is the difference between the MAX6070 and MAX6071?

The MAX6071 does not include the filter option present in the MAX6070, resulting in much faster turn-on and enable settling times.

How is the A grade defined for this component?

The A grade specifies a maximum temperature coefficient of 6ppm/°C, ensuring tighter thermal stability compared to lower grades.
