List of LM-series integrated circuits

LM393 differential comparator manufactured by National Semiconductor

The following is a list of LM-series integrated circuits. Many were among the first analog integrated circuits commercially produced; some were groundbreaking innovations, and many are still being used.[1] The LM series originated with integrated circuits made by National Semiconductor.[1][2] The prefix LM stands for linear monolithic, referring to the analog components integrated onto a single piece of silicon.[3] Because of the popularity of these parts, many of them were second-sourced by other manufacturers who kept the sequence number as an aid to identification of compatible parts.[2] Several generations of pin-compatible descendants of the original parts have since become de facto standard electronic components.[4]
