MAX6070DAUT12/V+T

Overview

The MAX6070DAUT12/V+T is a low-noise, high-precision series voltage reference from Analog Devices/Maxim Integrated. 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 within a supply voltage range of 2.7V to 5.5V, consuming a typical quiescent current of 200µA at +25°C. It supports bidirectional load currents up to ±10mA and features a filter pin for noise reduction. Packaged in a compact 6-pin SOT-23, it functions reliably across the extended industrial temperature range of -40°C to +125°C.

Feature Summary

Procurement Notes

Verify the specific suffix 'D' indicates the ±0.2% accuracy grade and 'AUT' denotes the automotive-grade WLP or SOT-23 package variant. Confirm RoHS compliance status through official documentation. Ensure the V+ designation aligns with lead-free requirements. Cross-reference the exact part number against the manufacturer's latest ordering guide to confirm availability and package type before procurement.

Selection Notes

Select this component when a 1.25V reference with ±0.2% initial accuracy is required. Consider the MAX6070 variant if low-pass filtering capability is needed for wideband applications. Evaluate the MAX6071 if faster settling times are critical and filtering is unnecessary. Ensure the supply voltage remains above the minimum dropout requirement for the desired load current.

Part Context

This part belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. These devices are designed for applications demanding enhanced system accuracy through low drift and low noise specifications. The family offers multiple output voltage options and packaging choices, including SOT-23 and wafer-level packages, suitable for space-constrained designs.

Replacement Considerations

MAX6070AAUT12/V+T: Offers higher accuracy (±0.04%) and lower drift (6ppm/°C).

FAQ

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

The FILTER pin allows connection of a capacitor to ground to provide high-frequency bypass, reducing output noise for wideband applications.

How does the MAX6070 differ from the MAX6071?

The MAX6070 includes a filter option for noise reduction but has slower turn-on and enable settling times compared to the MAX6071, which lacks the filter pin but offers faster response.
