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 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]
