MAX6070DAUT12/V+

Overview

The MAX6070DAUT12/V+ is a low-noise, high-precision series voltage reference in a 6-pin SOT-23 package. It provides a fixed output of 1.25V with an initial accuracy of ±0.2% and a maximum temperature drift of 20ppm/°C. The device operates from a supply voltage of 2.7V to 5.5V, consuming 150µA of supply current while sourcing or sinking up to 10mA of load current. It features a filter option for wideband applications and is specified 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 a low noise specification with a 1/f noise voltage of 6µVP-P at 0.1Hz to 10Hz
• Includes a filter input option to lower high-frequency noise for wideband applications
• Offers a shutdown mode that reduces supply current to 6µA

Applications

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

Procurement Notes

Verify the specific suffix 'D' indicates the ±0.2% accuracy grade and 'AUT' denotes the SOT-23-6 surface mount package. Confirm the '/V+' suffix aligns with RoHS compliance requirements for your manufacturing process. Ensure the component meets AEC-Q100 qualification standards if intended for automotive use. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Selection Notes

Select this part when a fixed 1.25V reference is required with moderate precision and low power consumption. The MAX6070 variant includes a filter pin suitable for reducing high-frequency noise, whereas the MAX6071 offers faster settling times without filtering. Consider the 20ppm/°C temperature drift limit against system accuracy requirements. Verify that the 150µA quiescent current fits within the total power budget of the application.

FAQ

What is the function of the FILTER pin on the MAX6070?

Connecting a 0.1µF capacitor from the FILTER pin to ground provides high-frequency bypass, lowering the output noise for wideband applications.

How does the MAX6070 differ from the MAX6071?

The MAX6070 includes a filter option for reduced high-frequency noise but has slower turn-on and enable settling times compared to the MAX6071.
