MAX6126B41+

Overview

The MAX6126B41+ is a series-mode voltage reference from Analog Devices/Maxim Integrated, housed in an 8-pin uMAX package. It provides a fixed output of 4.096V with a maximum initial accuracy of ±0.1% and a temperature coefficient of up to 3ppm/°C over the -40°C to +125°C range. The device operates on a supply voltage between 2.7V and 12.6V, drawing a typical quiescent current of 380µA. It supports sink/source currents up to 10mA and features low dropout voltage.

Feature Summary

• Features force and sense outputs for remote sensing to cancel line drops
• Includes a noise reduction pin for improved wideband noise performance
• Operates with stable load capacitance ranging from 0.1µF to 10µF

Applications

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

Procurement Notes

Verify the specific suffix 'B41+' against the manufacturer's official ordering guide to confirm the exact grade, package type, and output voltage specifications. Ensure compatibility with the required operating temperature range and electrical tolerances before procurement.

Selection Notes

Select this component when high precision and low noise are critical. The B-grade offers tighter accuracy than standard grades. Consider the uMAX package for space-constrained designs. Verify that the input voltage remains within the specified dropout limits for the intended load current.

Part Context

Part of the MAX6126 family of ultra-high-precision, ultra-low-noise series voltage references. This family utilizes curvature-correction circuitry and laser-trimmed thin-film resistors to achieve high stability and low temperature coefficients across various output voltages and packages.

Replacement Considerations

Check for MAX6126BASA41+ (SOIC package) or MAX6126B41+T (tape and reel). Verify pinout compatibility and thermal characteristics when substituting packages.
