Overview
The LM258DG is a dual operational amplifier (op-amp) produced by ON Semiconductor. It is part of the LM258 series, known for its low power drain and versatility in single supply or split supply operations. This device is particularly useful in applications requiring a wide range of supply voltages and robust input protection. The LM258DG is available in a Pb-free SOIC-8 package, making it suitable for various electronic designs where environmental considerations are important.
