MAX6126A41+T

Overview

The MAX6126A41+T is an ultra-low-noise, high-precision series voltage reference from Analog Devices/Maxim Integrated. It provides a fixed output of 4.096V with ±0.06% initial accuracy and a maximum temperature coefficient of 5ppm/°C over the -40°C to +125°C automotive range. The device operates on a supply voltage between 4.3V and 12.6V, drawing a typical quiescent current of 380µA. It features low dropout voltage, 10mA sink/source capability, and force/sense outputs for remote sensing.

Feature Summary

• Ultra-low noise architecture with flicker noise as low as 2.4µVP-P (0.1Hz to 10Hz) at 4.096V output
• Curvature-correction circuitry with laser-trimmed thin-film resistors for high stability
• Force and sense outputs enable remote sensing to cancel line drops
• 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
• High-accuracy industrial and process control systems

Procurement Notes

Verify the specific suffix '+T' indicates reel packaging when sourcing. Confirm the 'A' grade designation matches the required ±0.06% accuracy and 5ppm/°C tempco specifications for your application. Ensure the 4.096V output aligns with system requirements. Check for RoHS compliance status if mandated by your manufacturing standards.

Selection Notes

Select this component for applications requiring high precision in automotive or industrial environments. The 4.096V output is suitable for driving ADCs referenced to standard voltages. Consider the 5ppm/°C temperature coefficient for wide operating ranges. The low quiescent current makes it efficient for battery-powered designs where power conservation is critical.

Part Context

This part belongs to the MAX6126 family of ultra-high-precision, ultra-low-noise series voltage references. The family offers various output voltages including 2.048V, 2.5V, 3.0V, 3.3V, 3.6V, 4.096V, and 5.0V. The 'A' grade denotes tighter initial accuracy and temperature coefficient specifications compared to the 'B' grade variants within the same package type.

Replacement Considerations

MAX6126A41+ is the tube-packaged equivalent of the same electrical specification. MAX6126BASA41/V+ offers similar functionality but with B-grade accuracy (±0.06%) and 10ppm/°C tempco in an SOIC-8 package.
