MAX6226ALA33+T

Overview

The MAX6226ALA33+T is an ultra-low-noise, high-precision series voltage reference featuring a fixed 3.3V output. It operates within a supply voltage range of 3.5V to 12.6V and draws a typical quiescent current of 380µA. The device provides ±0.02% initial accuracy and a maximum temperature coefficient of 3ppm/°C over the -40°C to +125°C automotive temperature range. It includes force and sense outputs for remote sensing applications.

Feature Summary

• Hermetically sealed 8-pin ceramic LCC package ensures long-term stability and immunity to humidity-induced mechanical stress.
• Ultra-low noise architecture delivers 1.95µVP-P flicker noise (0.1Hz to 10Hz) with wideband noise reducible via an external capacitor on the NR pin.
• Low dropout capability allows operation with minimal input-to-output differential voltage while maintaining regulation.
• Independent force and sense outputs enable precise voltage regulation at the load point by compensating for trace resistance.

Applications

• High-resolution digital-to-analog converters
• Precision current sources
• High-accuracy industrial process control systems

Procurement Notes

Verify that the specific part number matches the required tape-and-reel packaging format indicated by the suffix. Confirm the manufacturer's RoHS compliance status through official documentation before integration. Ensure the design accommodates the specified hermetic ceramic package dimensions and thermal characteristics during PCB layout.

Selection Notes

Select this component when low noise and high precision are critical requirements for analog signal chains. The ceramic package is preferred for environments requiring superior long-term drift performance compared to plastic packages. Verify that the system supply voltage remains above the minimum dropout threshold to maintain stable regulation under all operating conditions.
