MAX6071AAUT12+T

Overview

The MAX6071AAUT12+T is a low-noise, high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed 1.25V output with ±0.04% initial accuracy and a maximum temperature drift of 6ppm/°C (A grade). The device operates within a supply voltage range of 2.7V to 5.5V, consuming 130µA to 200µA of quiescent current. It supports bidirectional load currents up to ±10mA and features an enable pin for shutdown control. Packaged in a compact 6-pin SOT23, it is specified over the extended industrial temperature range of -40°C to +125°C.

Procurement Notes

Verify the specific suffix 'AUT12' corresponds to the 1.25V output variant and the 'A' grade for the 6ppm/°C temperature coefficient limit. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number directly with official Analog Devices documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this component when a stable 1.25V reference is required in space-constrained designs. The MAX6071 offers superior noise characteristics compared to standard references. Consider the MAX6070 if a filter option is needed for wideband applications. Verify that the input voltage remains above the dropout threshold across the full operating temperature range to maintain regulation.

Part Context

This component 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 internal filter capacitor, offering faster transient response times. Both devices share similar electrical specifications but cater to different noise filtering requirements in precision measurement systems.

Replacement Considerations

Direct replacements include other MAX6071 variants with different output voltages or grades. Verify pin compatibility and thermal characteristics when substituting.
