MAX6126A30+T

Overview

The MAX6126A30+T is a series-mode voltage reference with a fixed 3.000V output, housed in an 8-pin SOIC package. It features ±0.02% initial accuracy and a maximum temperature coefficient of 3ppm/°C over the -40°C to +85°C range. The device operates from a supply voltage between 3.2V and 12.6V, drawing a typical quiescent current of 380μA. It supports up to 10mA sink/source current with a maximum dropout voltage of 0.2V.

Feature Summary

• Ultra-low noise architecture with flicker noise as low as 1.75μVP-P (0.1Hz to 10Hz) for high-precision signal chains
• Curvature-correction circuitry ensures high stability and minimal drift across wide temperature ranges
• Force and sense outputs enable remote sensing to cancel line drops for enhanced measurement accuracy

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the 'A' grade designation matches the required ±0.02% accuracy specification for your application. Ensure the 8-pin SOIC footprint aligns with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this part when ultra-low noise and high precision are critical requirements. The series-mode operation eliminates the need for external resistors found in shunt references. Consider the 3.000V output level against system requirements and ensure the input voltage remains above the minimum dropout threshold for optimal regulation.
