MAX6226ALA25+

Overview

The MAX6226ALA25+ is an ultra-low-noise, high-precision series voltage reference featuring a fixed 2.500V output with ±0.02% initial accuracy and a maximum temperature coefficient of 3ppm/°C over the -40°C to +125°C automotive range. It operates from a 2.7V to 12.6V supply with a typical quiescent current of 380μA and dropout voltage as low as 200mV. The device provides 10mA sink/source capability, 11ppm/1000hr long-term drift, and includes force/sense outputs for remote sensing.

Feature Summary

• Hermetically sealed 8-pin ceramic LCC package eliminates humidity-induced die stress and improves long-term stability
• Proprietary architecture delivers ultra-low flicker noise without increasing supply current
• Independent force and sense outputs enable Kelvin connections to cancel trace voltage drops
• Curvature-correction circuitry ensures high precision across wide operating temperatures

Applications

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

Procurement Notes

Verify the specific suffix indicates RoHS compliance status only. Confirm the package code matches the required hermetic ceramic form factor. Ensure the ordering designation aligns with the intended temperature grade and output voltage tolerance requirements for your design.

Selection Notes

Select this component when ultra-low noise and high precision are critical. The ceramic package offers superior stability compared to plastic alternatives. Verify that the load capacitance remains within the stable range and that the supply voltage accommodates the minimum dropout requirements under all operating conditions.

Part Context

This part belongs to the MAX6226 family of ultra-high-precision voltage references. It shares architectural features with other members like the MAX6226ALA33+ and MAX6226ALA50+, differing primarily in the fixed output voltage setting while maintaining identical noise, accuracy, and packaging specifications.

Replacement Considerations

Direct replacements include MAX6226ALA33+ and MAX6226ALA50+ for different voltage needs. Cross-brand equivalents require matching hermetic packaging, noise specs, and temperature coefficients.
