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]

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 ,[ 97] 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.[ 98]
Some obsolete parts continue to be manufactured by different companies other than the original manufacturer.
