MAX6071AAUT18+T

Overview

The MAX6071AAUT18+T is a low-noise, high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 1.8V 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 2.7V to 5.5V and consumes a typical supply current of 150µA at +25°C. It supports sourcing and sinking up to 10mA of load current and features a shutdown supply 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.

Feature Summary

• Provides stable performance over temperature and time with high initial accuracy
• Features very low noise and low-drift specifications for enhanced system accuracy
• Includes an enable pin for power management and shutdown control
• Offers remote sense capability via dedicated force and sense outputs

Applications

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

Procurement Notes

Verify the specific suffix 'AUT18' confirms the 1.8V output voltage and SOT-23-6 packaging. Ensure the 'A' grade designation matches the required 6ppm/°C maximum temperature drift specification. Confirm RoHS compliance status if environmental regulations apply to the target assembly process.

Selection Notes

Select this component when a fixed 1.8V precision reference is required in a small footprint. It is suitable for applications demanding low noise and minimal power consumption. Consider the MAX6070 variant if a filter option for wideband noise reduction is needed instead of the standard MAX6071 configuration.

Part Context

This part belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. The family shares similar electrical characteristics but differs in features like filtering options and available output voltages. These devices are designed to replace standard LDO regulators in precision analog signal chains where stability and accuracy are critical.

Replacement Considerations

MAX6070AAUT18+T serves as a functional substitute with identical electrical parameters but includes a filter input pin.
