MAX6126BASA21+T

Overview

The MAX6126BASA21+T is a series-mode voltage reference from Analog Devices/Maxim Integrated, housed in an 8-pin SO package. It provides a fixed output of 2.048V with a maximum initial accuracy of ±0.06% and a temperature coefficient of 5ppm/°C over the -40°C to +85°C range. The device operates within a supply voltage range of 2.7V to 12.6V, drawing a typical quiescent current of 380μA. It supports up to 10mA sink/source current capability and maintains stability with load capacitances between 0.1μF and 10μF.

Feature Summary

• Features curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Provides independent force and sense outputs (OUTF/OUTS) for remote sensing applications.
• Operates with low dropout voltage and virtually constant supply current across the input range.

Applications

• High-Resolution A/D and D/A Converters
• Precision Current Sources
• Digital Voltmeters
• High-Accuracy Industrial and Process Control

Procurement Notes

Verify the specific suffix 'B' indicates B-grade accuracy (±0.06%) and 'SA' denotes the SOIC-8 package. Confirm the '+T' suffix corresponds to tape-and-reel packaging if reel quantity is required. Ensure the component meets RoHS compliance standards as indicated by the '+' designation. Cross-reference the manufacturer part number against official distributor catalogs to confirm availability status.

Selection Notes

Select this component when a fixed 2.048V reference with B-grade accuracy is required in an SO package. It is suitable for designs needing low noise and wide supply voltage tolerance. Consider the A-grade variant if tighter accuracy specifications are necessary. Evaluate thermal performance and ensure adequate heat dissipation within the SO package constraints for the target application environment.

Part Context

This component belongs to the MAX6126 family of ultra-high-precision, ultra-low-noise series voltage references. The family includes various output voltages and packages, such as μMAX and SO. The MAX6126 series is designed for applications demanding stable reference voltages with minimal drift and noise, utilizing proprietary architecture to achieve low flicker noise without increased supply current.

Replacement Considerations

The MAX6126AASA21+ serves as a higher-accuracy alternative within the same package type. Other MAX6126 variants offer different output voltages or package styles like μMAX. Verify pin compatibility and electrical specifications before substituting with other series references.
