LM4140 Voltage Reference Series

ti

The LM4140 series voltage reference ICs from Texas Instruments are designed to provide stable, accurate references in a variety of applications. These ICs come in an 8-SOIC package and are available in different fixed output voltages, including 1.25V, 1.024V, 2.048V, and others. Each variant is specified to deliver a precision reference voltage with low drift and high stability over temperature and time. If you're working on power supply designs, analog circuits, or any system that requires a stable reference voltage, these ICs are a go-to choice. They are particularly useful in applications like precision amplifiers, ADC/DAC reference supplies, and general-purpose reference voltages where accuracy and stability are critical. Engineers tend to reach for this when they need a reliable and precise reference that can operate across a wide range of input voltages and maintain stability over time. One practical observation is that the LM4140 series is known for its low power consumption, making them suitable for battery-powered devices. Additionally, their low dropout voltage means they can operate effectively even when the supply voltage is close to the reference voltage, which is bene
