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

Notes Suffixes that denote specific versions of the part (e.g. LM305 vs. LM305A) are not shown in this list. Obsolete 4-bit microprocessors of the LM6400 family, manufactured by Sanyo, have no relationship to the analog LM series and are not included in this list. The first digit of each part denote different temperature ranges. Mostly, LM1xx indicates military-grade temperature range of -55 °C to +125 °C, LM2xx indicates industrial-grade temperature range of -25 °C to +85 °C and LM3xx indicates commercial temperature range of 0 °C to 70 °C. Some obsolete parts continue to be manufactured by different companies other than the original manufacturer.
