MAX6070BAUT33/V+

Overview

The MAX6070BAUT33/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 ±0.08% and a maximum temperature drift of 8ppm/°C. The device operates on a supply voltage from 3.5V to 5.5V, consuming 330µA of supply current. It supports up to 10mA of load current and includes an enable pin for power management.

Feature Summary

• Provides stable performance over temperature and time with high initial accuracy
• Features a filter option to lower high-frequency noise for wideband applications
• Includes an enable input for shutdown control to reduce power consumption

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 'V+' indicates RoHS compliance status only, as per manufacturer documentation. Confirm the part number matches the exact grade (B) and output voltage (3.3V). Check for any obsolete or end-of-life notices from Analog Devices. Ensure the ordering code aligns with the required packaging format.

Selection Notes

Select this component when a fixed 3.3V reference with B-grade accuracy is required. Consider the MAX6070AAUT33/V+ if tighter ±0.04% accuracy and lower drift are needed. Evaluate the MAX6071 variant if Kelvin sense outputs are necessary for remote sensing applications. Verify that the 3.5V minimum input voltage suits the system design.

Part Context

This part belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. The MAX6070 offers a filter option, while the MAX6071 provides separate force and sense outputs. Both families share similar electrical characteristics but differ in package options and feature sets.
