MAX6070BAUT21+T

Overview

The MAX6070BAUT21+T is a low-noise, high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.048V with an initial accuracy of ±0.08% at +25°C and a maximum temperature drift of 8ppm/°C. The device operates within a supply voltage range of 2.7V to 5.5V and consumes a typical quiescent current of 200µA. It supports bidirectional load currents up to 10mA and features a shutdown mode with current consumption as low as 6µA. The component is housed in a compact 6-pin SOT23 package and is specified for operation across the extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Provides stable performance over temperature and time with high initial accuracy and low temperature drift.
• Features a filter option on the MAX6070 variant to lower high-frequency noise for wideband applications.
• Offers low dropout voltage and high ripple rejection to maintain regulation under varying line conditions.
• Includes an enable input for power management, allowing the device to be disabled to minimize supply current.

Applications

• High-Accuracy Industrial and Process Control
• Precision Instrumentation
• High-Resolution ADCs and DACs
• Precision Current Sources

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing from distributors. Confirm that the 'B' grade designation corresponds to the ±0.08% accuracy and 8ppm/°C drift specifications required for the design. Ensure the ordering part number matches the exact output voltage and package type needed for the PCB layout.

Selection Notes

Select this component when a fixed 2.048V reference is required with tighter accuracy than the 'A' grade offers. The MAX6070 variant should be chosen if internal filtering is desired to reduce high-frequency noise without external components. Consider the MAX6071 if faster turn-on settling times are critical for the application timing requirements.

Part Context

This part belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. The family is designed to provide enhanced system accuracy through low-drift and low-noise specifications. Variants within the family differ primarily in accuracy grades (A, B, D), noise filtering capabilities, and specific output voltage options ranging from 1.25V to 5.0V.
