MAX6071BAUT25+T

Overview

The MAX6071BAUT25+T is a low-noise, high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.08% and a maximum temperature drift of 8ppm/°C. The device operates within an input voltage range of 2.7V to 5.5V and consumes a typical supply current of 200µA 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 over the extended industrial temperature range of -40°C to +125°C.

Procurement Notes

Verify the specific suffix 'AUT25' corresponds to the required 2.5V output, B grade accuracy, and SOT-23 package configuration. Confirm that the '+T' designation indicates tape-and-reel packaging if applicable to your assembly process. Ensure compatibility with the 2.7V to 5.5V input voltage range and check for any RoHS compliance requirements relevant to your manufacturing standards.

Selection Notes

Select this component when a fixed 2.5V reference with ±0.08% accuracy and 8ppm/°C drift is required. It is suitable for designs needing bidirectional current capability and low power consumption. Consider the SOT-23 package size constraints and the need for external bypass capacitors as specified in the datasheet. Evaluate thermal performance if operating near the upper temperature limits.

Part Context

This part belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. The MAX6071 variant specifically lacks the filter option present in the MAX6070. The family offers various output voltages and grades (A, B, D) to meet different precision and cost requirements. These devices are designed for applications demanding enhanced system accuracy through low-drift and low-noise specifications.

Replacement Considerations

Direct substitutes include other parts from the MAX6070/MAX6071 family with matching output voltage and accuracy grades, such as MAX6071AAUT25+T for higher precision or MAX6071DAUT25+T for lower cost. Verify package compatibility and electrical specifications before substitution.
