MAX6126A50+T

Overview

The MAX6126A50+T is a series-mode voltage reference with a fixed 5.000V output, housed in an 8-pin SOIC package. It offers ±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 5.2V and 12.6V, drawing a typical quiescent current of 380µA. It supports up to 10mA sink/source current with a maximum dropout voltage of 0.4V.

Feature Summary

• Features independent force and sense outputs for remote sensing to cancel line drops
• Includes a noise reduction pin for improved wideband noise performance
• Utilizes curvature-correction circuitry and laser-trimmed thin-film resistors

Applications

• High-Resolution A/D and D/A Converters
• ATE Equipment
• Precision Current Sources

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the '+A' designation matches the required ±0.02% accuracy grade. Ensure the '+T' suffix aligns with the 8-SOIC package type. Cross-reference the manufacturer part number against official Analog Devices documentation to confirm RoHS compliance and lead-free status before procurement.

Selection Notes

Select this component for applications requiring high precision and low noise without external resistors. The series architecture eliminates waste associated with shunt references. Verify that the input voltage exceeds the minimum requirement of 5.2V. Consider the 8-SOIC package dimensions for PCB layout constraints. Evaluate the need for remote sensing capabilities if trace resistance impacts system accuracy.
