MAX6071BAUT18+T

Overview

The MAX6071BAUT18+T is a low-noise, high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output of 1.8V with an initial accuracy of ±0.08% and a maximum temperature drift of 8ppm/°C. The device operates within a supply voltage range of 2.7V to 5.5V, consuming a typical quiescent current of 200µA at +25°C. It supports bidirectional load currents up to ±10mA and features a shutdown mode drawing only 6µA. Packaged in a compact 6-pin SOT-23 format, it 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 1/f noise and low thermal noise characteristics
• Includes an enable pin for power management and shutdown control
• Offers remote sense outputs (OUTS) to compensate for trace resistance

Applications

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

Procurement Notes

Verify the specific suffix 'AUT18' corresponds to the 1.8V output variant and 'B' grade accuracy when sourcing. Confirm the package type matches the required PCB footprint. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Selection Notes

Select this component for applications requiring precise voltage references in space-constrained designs. The B-grade accuracy suits systems needing tighter tolerances than standard grades. Consider the low dropout voltage and high ripple rejection for noisy environments. Evaluate the enable functionality against system power sequencing requirements.

Part Context

This device belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. The MAX6071 variant distinguishes itself from the MAX6070 by omitting the filter input pin, resulting in faster turn-on settling times. Both share similar electrical characteristics but cater to different noise filtering needs.

Replacement Considerations

Direct replacements include other parts from the MAX6071 series with different output voltages or accuracy grades, such as MAX6071AAUT18+T or MAX6071CAUT18+T. Verify pin compatibility and electrical specifications before substitution.
