List of LM-series integrated circuits

The following is a list of LM-series integrated circuits. Many were among the first analog integrated circuits commercially produced; some were groundbreaking innovations, and 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.
