MAX6126A41+

Overview

The MAX6126A41+ is a series-mode voltage reference with a fixed output of 4.096V, housed in an 8-pin SO package. It features a maximum initial accuracy of ±0.02% and a temperature coefficient of 3ppm/°C over the -40°C to +85°C range. The device operates within a supply voltage range of 4.3V to 12.6V, drawing a typical quiescent current of 380µA. It supports up to 10mA of sink/source current capability.

Feature Summary

• Ultra-low noise architecture providing flicker noise as low as 1.3μVP-P without increasing supply current
• Curvature-correction circuitry combined with laser-trimmed thin-film resistors for high stability
• Independent force and sense outputs (OUTF and OUTS) enable remote sensing to cancel line drops

Applications

• High-resolution A/D and D/A converters
• ATE equipment requiring stable references
• Precision current sources
• Digital voltmeters

Procurement Notes

Verify the specific suffix 'A' indicates the highest precision grade (+/- 0.02%) and '41' denotes the 4.096V output variant. Confirm the 'SO' package designation matches your PCB footprint requirements. Ensure the input voltage source can handle transient currents during turn-on if operating near minimum dropout conditions.

Selection Notes

Select this component when ultra-high precision and low noise are critical for signal chain integrity. The wide supply voltage range accommodates various power rails, while the low dropout voltage allows operation close to the output level. Consider the NR pin for additional noise reduction if system bandwidth permits increased settling time.

Part Context

This part belongs to the MAX6126 family of ultra-high-precision, ultra-low-noise series voltage references. The family utilizes proprietary low-noise architecture and curvature correction to achieve exceptional performance metrics across multiple fixed output voltages and packaging options.
