MAX6070DAUT30/V+T

Overview

The MAX6070DAUT30/V+T is a low-noise, high-precision series voltage reference from Analog Devices. It provides a fixed output of 3.0V with an initial accuracy of ±0.2% and a maximum temperature drift of 20ppm/°C. The device operates within a supply voltage range of 3.5V to 5.5V and consumes a typical quiescent current of 160µA 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, it is specified over the extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Integrated enable pin for power management via logic-level control
• Capable of sourcing and sinking up to 10mA of load current
• Low noise performance suitable for precision analog circuits
• Extended industrial temperature operation for harsh environments

Applications

• High-accuracy industrial process control systems
• Precision instrumentation signal conditioning
• High-resolution ADCs and DACs reference sources
• Automotive sensor interfaces

Procurement Notes

Verify the specific suffix 'V+' indicates AEC-Q100 automotive qualification status as per official documentation. Confirm package type matches the required SOT-23 footprint. Ensure the ordering code corresponds to the correct output voltage grade and accuracy class before finalizing procurement orders.

Selection Notes

Select this component when a 3.0V reference is required with moderate accuracy. The D-grade offers lower precision than A or B grades but maintains low noise. Consider the MAX6071 variant if the internal filter option is not needed for faster settling times. Verify input voltage headroom against the dropout specifications for the target load conditions.

Part Context

This part belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. These devices are designed to enhance system accuracy in demanding applications. The family includes various output voltages and accuracy grades, packaged in small form factors like SOT-23 and WLP to minimize board space usage.

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 wideband noise for applications requiring reduced high-frequency interference.

How does the MAX6070 differ from the MAX6071 regarding grounding?

The MAX6070 utilizes separate Ground Force (GNDF) and Ground Sense (GNDS) pins to minimize thermal EMF errors, whereas the MAX6071 uses a single common ground pin.
