The following is a list of LM-series integrated circuits. Many were among the first analog integrated circuits commercially produced since late 1965;[1] some were groundbreaking innovations[opinion]. As of 2007, many are still being used.[2] The LM series originated with integrated circuits made by National Semiconductor.[2][3] The prefix LM stands for linear monolithic, referring to the analog components integrated onto a single piece of silicon.[4] 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.[3] Several generations of pin-compatible descendants of the original parts have since become de facto standard electronic components.[5]
