MAX6126AASA30+T

Overview

The MAX6126AASA30+T is a series voltage reference from Analog Devices/Maxim Integrated, housed in an 8-pin SOIC package. It provides a fixed output voltage of 3V with a maximum initial accuracy of ±0.02% and a maximum temperature coefficient of 3ppm/°C over the -40°C to +85°C range. The device operates within a supply voltage range of 3.2V to 12.6V, drawing a typical quiescent current of 380µA. It supports sink/source currents up to 10mA and maintains stability with load capacitances between 0.1µF and 10µF.

Feature Summary

• Ultra-low noise architecture featuring curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Independent force (OUTF) and sense (OUTS) outputs enable remote sensing to cancel voltage drops on connecting lines.
• Low dropout capability allows operation with minimal input-to-output voltage differential while maintaining regulation.
• Supply current remains virtually independent of the input supply voltage across the specified operating range.

Applications

• High-resolution analog-to-digital and digital-to-analog converters
• Automated test equipment requiring stable reference voltages
• Precision current sources utilizing the force and sense outputs
• Digital voltmeters and high-accuracy industrial process control systems

Procurement Notes

Verify the specific suffix 'A' indicates A-grade accuracy (+/-0.02%) and 'SA' denotes the SOIC-8 package configuration. Confirm the '+T' suffix corresponds to tape-and-reel packaging if required by assembly equipment. Ensure the input supply voltage exceeds the minimum threshold of 3.2V for proper operation at the 3V output level.

Selection Notes

Select this component when ultra-low noise and high initial accuracy are critical for signal integrity. The wide supply voltage range accommodates various power rails without external regulation. Consider the thermal performance and long-term stability requirements against the specified ppm/1000hr drift characteristics for precision measurement applications.
