Overview
The LM324NE4 is a quad operational amplifier produced by Texas Instruments. It is part of the next-generation versions of the industry-standard operational amplifiers, including the LM324 and LM2902 series. This device is designed to provide high performance and value for cost-sensitive applications. It features four high-voltage (up to 36 V) operational amplifiers, making it suitable for a wide range of applications that require multiple amplification stages.
The LM324NE4 is known for its low input offset voltage, common-mode input range to ground, and high differential input voltage capability. It is unity-gain stable and offers low quiescent current per amplifier, along with high ESD protection and integrated EMI and RF filters, making it robust for use in environmentally challenging conditions.
