MAX6226ALA50+

Overview

The MAX6226ALA50+ is an ultra-low-noise, high-precision series voltage reference with a fixed 5.0V output. It features a maximum temperature coefficient of 3ppm/°C and initial accuracy of ±0.02%. The device operates from a supply voltage range of 5.2V to 12.6V with a typical quiescent current of 380µA. It provides 10mA sink/source capability and includes force/sense outputs for remote sensing.

Feature Summary

• Hermetically sealed 8-pin ceramic LCC package
• Ultra-low flicker noise architecture
• Independent force and sense outputs
• Low dropout voltage operation

Applications

• High-resolution A/D and D/A converters
• ATE equipment
• Precision current sources
• Digital voltmeters

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing. Confirm the 'A' grade designation matches the required ±0.02% accuracy and 3ppm/°C temperature coefficient specifications. Ensure the hermetic ceramic package aligns with environmental requirements.

Selection Notes

Select this component for applications requiring minimal long-term drift and low noise without excessive power consumption. The independent force and sense pins are critical for maintaining accuracy over long trace lengths. Verify that the input voltage remains above the minimum dropout threshold across all operating conditions.

Part Context

This part belongs to the MAX6226 family of precision references. It utilizes curvature-correction circuitry and laser-trimmed thin-film resistors. The device is designed for automotive temperature ranges (-40°C to +125°C) and offers superior stability compared to plastic-packaged alternatives due to its hermetic construction.
