Four independent channels ensure precision and reliability

LM224ADR General Description

With the introduction of the LM224ADR, designers can now benefit from a next-generation operational amplifier that combines industry-standard performance with enhanced features for superior value. The device's low offset voltage and high-voltage capability make it suitable for a variety of applications, from consumer electronics to industrial controls. Its unity-gain stability and low quiescent current per amplifier ensure efficient operation and extended battery life in portable devices. Additionally, the LM224ADR's compatibility with previous LM224, LM324, and LM2902 devices simplifies the transition to this advanced model, offering a seamless upgrade path for existing designs. Thanks to its high ESD rating and integrated EMI/RF filters, the LM224ADR can withstand challenging environmental conditions and provide reliable performance in demanding situations
