MAX6070DAUT25/V+T

Overview

The MAX6070DAUT25/V+T is a low-noise, high-precision series voltage reference in a 6-pin SOT-23 package. It provides a fixed output of 2.5V with ±0.2% initial accuracy and a maximum temperature drift of 20ppm/°C. The device operates on an input voltage range of 2.8V to 5.5V, consuming 150µA supply current while sourcing or sinking up to 10mA load current. It features a filter option for wideband noise reduction and is specified over the -40°C to +125°C temperature range.

Feature Summary

• Provides stable performance over temperature and time with high initial accuracy
• Features a dedicated filter pin to lower high-frequency noise for wideband applications
• Includes enable control functionality to reduce power consumption during inactive periods

Applications

• High-accuracy industrial and process control systems
• Precision instrumentation equipment
• High-resolution ADCs and DACs
• Precision current sources
• Automotive electronics

Procurement Notes

Verify the specific suffix 'D' indicates the D grade with ±0.2% accuracy and 20ppm/°C drift, distinct from A or B grades. Confirm the '/V+' suffix denotes automotive qualification status per the official ordering guide. Ensure the 'AUT' designation matches the required operating temperature range and reliability standards for your specific application environment.

Selection Notes

Select this component when a fixed 2.5V reference is required with moderate precision and low quiescent current. The MAX6070 variant includes a filter pin suitable for reducing wideband noise, whereas the MAX6071 lacks this feature but offers faster settling times. Consider the dropout voltage requirements relative to the minimum input voltage available in the system design.

Part Context

This part belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family is designed to enhance system accuracy in high-precision applications through low drift and low noise specifications. Variants are available in both SOT-23 and WLP packages, covering common voltage levels from 1.25V to 5.0V.
