MAX6173BASA/V+

Overview

The MAX6173BASA/V+ is a high-precision voltage reference providing a fixed +2.5V output with ±0.1% initial accuracy and a maximum temperature coefficient of 10ppm/°C over the -40°C to +125°C range. It accepts input voltages from (VOUT + 2V) up to +40V, draws 450µA maximum supply current, and sources 30mA or sinks 2mA load current. The device includes a linear temperature sensor output proportional to die temperature and a TRIM pin for fine adjustment. It operates without an external output bypass capacitor for stability.

Feature Summary

• Features proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Includes a dedicated TEMP pin providing a voltage output proportional to the internal die temperature.
• Offers a TRIM input pin allowing fine adjustment of the output voltage via an external resistive divider.
• Provides short-circuit protection limiting output current when connected to ground or input.

Applications

• High-resolution Analog-to-Digital Converters (ADCs)
• Digital-to-Analog Converters (DACs)
• Automotive electronic systems
• Precision digital voltmeters

Procurement Notes

Verify that the specific part number suffix /V confirms AEC-Q100 automotive qualification status as indicated in the manufacturer's ordering information section. Ensure the component matches the 8-pin SO package outline and confirm RoHS compliance through official documentation before integration into production designs.

Selection Notes

Select this component when a stable +2.5V reference is required alongside integrated temperature sensing capabilities. It is suitable for applications demanding low noise and high accuracy without the board space penalty of external stabilization capacitors. Consider the 10ppm/°C temperature coefficient limit for wide operating temperature environments.

Part Context

This device belongs to the MAX6173–MAX6177 family of high-precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family shares identical architecture and features, differing primarily in their preset output voltage levels ranging from +2.5V to +10V and specific accuracy grades.

Replacement Considerations

Compatible substitutes within the same family include MAX6173AASA+ and MAX6173BASA+. Verify that alternative part numbers match the required output voltage, accuracy grade, and package type before substitution.
