MAX6070AAUT33/V+

Overview

The MAX6070AAUT33/V+ is a low-noise, high-precision series voltage reference in a 6-pin SOT-23 package. It provides a fixed output of 3.3V with an initial accuracy of ±0.04% and a maximum temperature drift of 6ppm/°C. The device operates within a supply voltage range of 3.5V to 5.5V, consuming a typical quiescent current of 160µA at +25°C. It supports up to 10mA of load current sourcing or sinking. Key dynamic characteristics include 1/f noise of 10µVp-p (0.1Hz to 10Hz) and thermal noise of 9µVrms (10Hz to 10kHz). It features a filter input for wideband noise reduction and an enable pin for shutdown control.

Feature Summary

Procurement Notes

Verify the specific suffix 'V+' against the manufacturer's official documentation to confirm RoHS compliance status and lead time constraints. Confirm availability as distributor listings may indicate limited stock or discontinuation status. Ensure the ordering code matches the required A-grade specifications for accuracy and drift parameters.

Selection Notes

Select this component when a stable 3.3V reference is required in a compact SOT-23 form factor. Consider the MAX6070 variant if wideband noise filtering via the FILTER pin is necessary. Verify that the input voltage remains within the 3.5V to 5.5V range to ensure proper regulation and dropout voltage margins under all operating conditions.

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 MAX6070 includes a filter input, while the MAX6071 does not. Both are designed for enhanced system accuracy in high-precision applications, offering stability over temperature and time in small packages.

Replacement Considerations

Consult the official datasheet selector guide for direct replacements with different output voltages or grades. Cross-reference with other Maxim Integrated series voltage references ensuring compatible package dimensions and electrical specifications such as noise and drift.
