MAX6071AAUT21+T

Overview

The MAX6071AAUT21+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 ±0.04% at +25°C and a maximum temperature drift of 6ppm/°C (A grade). The device operates within a supply voltage range of 2.7V to 5.5V, consuming a typical quiescent current of 150µA. It features a 1/f noise voltage of 6.4µVP-P (0.1Hz to 10Hz) and supports bidirectional load currents up to ±10mA. Packaged in a compact 6-pin SOT23, it is specified over the extended industrial temperature range of -40°C to +125°C.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with the target application's voltage requirements and environmental conditions. Confirm RoHS compliance status through manufacturer datasheets or authorized distributors before procurement.

Selection Notes

Select this component when low noise and high precision are critical for signal integrity. Consider the 2.048V output level for compatibility with standard data converter reference inputs. Evaluate the power budget against the 150µA supply current requirement. Verify that the SOT23 package fits the available footprint constraints.

Part Context

This part belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. The MAX6071 variant specifically lacks the filter option present in the MAX6070, offering faster turn-on settling times. The family is designed for applications demanding superior accuracy and stability across wide temperature ranges.

Replacement Considerations

Direct replacements include other MAX6071 variants with different output voltages such as MAX6071AAUT25+T or MAX6071AAUT33+T. Cross-referencing with Maxim Integrated or Analog Devices documentation is required to ensure pinout and electrical parameter compatibility.
