List of LM-series integrated circuits
From Wikipedia, the free encyclopedia

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.
