MAX6126A28+T

Overview

The MAX6126A28+T is a series-mode voltage reference with a fixed output of 2.800V, housed in an 8-pin μMAX package. It features a maximum initial accuracy of ±0.06% and a temperature coefficient of 3ppm/°C over the -40°C to +85°C range. The device operates within a supply voltage range of 3.0V to 12.6V, drawing a typical quiescent current of 380μA. It supports sink/source currents up to 10mA 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 capability.
• 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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing from distributors. Confirm the 'A' grade designation matches the required ±0.06% accuracy specification. Ensure the 8-pin μMAX footprint aligns with the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a stable 2.800V reference is required with minimal noise and high accuracy. Consider the 8-pin μMAX package for space-constrained designs. Evaluate the need for Kelvin connections if trace resistance impacts system accuracy requirements.

Part Context

This part belongs to the MAX6126 family of ultra-high-precision, ultra-low-noise series voltage references manufactured by Analog Devices / Maxim Integrated. The family offers various output voltages and packages, utilizing proprietary low-noise architecture to achieve excellent performance without excessive supply current consumption.

Replacement Considerations

Cross-reference other MAX6126 variants such as MAX6126A28+ for tube packaging or MAX6126BASA28+ for SOIC packages if pinout compatibility is maintained. Verify that alternative parts meet the same ±0.06% accuracy and 3ppm/°C temperature coefficient specifications.
