MAX6070BAUT21/V+T

Overview

The MAX6070BAUT21/V+T is a low-noise, high-precision series voltage reference in a 6-pin SOT-23 package. It provides a fixed output of 2.048V with an initial accuracy of ±0.08% and a maximum temperature drift of 8ppm/°C (B grade). The device operates on a supply voltage from 2.7V to 5.5V, consuming 150µA typical supply current. It supports up to 10mA load current sourcing and sinking, features a filter pin for noise reduction, and includes an enable control.

Feature Summary

• Integrated filter input allows connection of a capacitor to reduce high-frequency noise for wideband applications
• Capable of sourcing and sinking up to 10mA of load current while maintaining stability
• Includes an enable pin for power management and system shutdown control

Applications

• High-accuracy industrial and process control systems
• Precision instrumentation requiring stable references
• High-resolution ADCs and DACs
• Precision current sources
• Automotive electronics

Procurement Notes

Verify the specific suffix 'V+' indicates automotive qualification status as per official documentation. Confirm the 'AUT' designation aligns with your required operating temperature range and reliability standards. Ensure the ordering code matches the exact B-grade accuracy and 2.048V output specification needed for your design.

Selection Notes

Select this component when a fixed 2.048V reference is required with low noise and high precision. The MAX6070 variant offers a filter option for superior high-frequency noise performance compared to the MAX6071. Consider the B-grade specifications if tighter than A-grade tolerances are not necessary but lower cost is desired.

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 environments. The family is available in various output voltages and packages, including SOT-23 and WLP, catering to space-constrained designs.

Replacement Considerations

MAX6070AAUT21/V+T: Offers higher A-grade accuracy (±0.04%) and lower drift (6ppm/°C max) compared to the B-grade version.

FAQ

What is the function of the FILTER pin?

The FILTER pin allows the 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 input pin for noise reduction, whereas the MAX6071 does not have this feature.
