LM4040CYM3-4.1-TR: Precision 4.1V Voltage Reference for Stable Circuit Performance

In the world of precision electronics, maintaining a stable voltage reference is paramount for the accuracy and reliability of countless applications, from data converters and power supplies to portable instruments and automotive systems. The LM4040CYM3-4.1-TR stands out as a critical component engineered to deliver exceptional performance in this role.

This device is a precision 4.1V shunt voltage reference, available in a space-saving SOT-23 surface-mount package. Its primary function is to provide a fixed, stable voltage regardless of changes in input voltage, load current, or ambient temperature. The LM4040CYM3-4.1-TR achieves this with a remarkable initial accuracy of up to ±0.1% (A-grade), ensuring that designers have a highly reliable benchmark voltage for their most demanding circuits.

A key to its stable performance is its low dynamic impedance, typically just 0.5Ω, which allows the reference voltage to remain steady even as the operating current fluctuates. Furthermore, it is designed with low-noise operation, making it an ideal choice for noise-sensitive applications like precision sensors and high-resolution analog-to-digital converters (ADCs).

The device is exceptionally easy to use, requiring only a single external resistor to set the operating current. Its wide operating current range, from 60µA to 12mA, provides designers with significant flexibility, enabling its use in both power-conscious, battery-operated devices and more traditional line-powered equipment. The LM4040CYM3-4.1-TR is also designed for stability over time and temperature, featuring a low temperature coefficient to minimize drift.
