MAX6126A25+

Overview

The MAX6126A25+ is a series-mode voltage reference with a fixed 2.5V output, housed in an 8-pin uMAX package. It features ±0.06% initial accuracy and a maximum temperature coefficient of 3ppm/°C over the -40°C to +85°C range. The device operates from a 2.7V to 12.6V supply, draws 380µA typical quiescent current, and supports up to 10mA sink/source load current.

Feature Summary

• Ultra-low noise architecture with curvature-correction circuitry
• Independent force and sense outputs for remote sensing
• Stable with capacitive loads 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 'A' indicates the accuracy grade and 'uMAX' denotes the package type. Confirm RoHS compliance status via official documentation. Ensure the ordering code matches the required thermal performance specifications for the intended operating environment.

Selection Notes

Select this component when high precision and low noise are critical. The uMAX package suits space-constrained designs. Verify that the input voltage remains within the specified dropout limits relative to the 2.5V output under all load conditions.

Part Context

Part of the MAX6126 family of ultra-high-precision, ultra-low-noise series voltage references. Designed for applications requiring stable reference voltages with minimal drift and noise across wide temperature ranges.

Replacement Considerations

Check pinout compatibility with SOIC-8 variants if board space allows. Verify electrical parameters match requirements before substituting with other Maxim Integrated or Analog Devices precision references.
