  2. LM386 - Wikipedia

    en.wikipedia.org/wiki/LM386

    The LM386 is an integrated circuit containing a low-voltage audio power amplifier. [1] It is suitable for battery-powered devices such as radios, guitar amplifiers, and hobby electronics projects. The IC consists of an 8-pin dual in-line package (DIP-8) and can output 0.25 to 1 watts of power, depending on the model, using a 9-volt power supply.

    en.wikipedia.org/wiki/List_of_LM-series...

    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 ...

  5. Electret microphone - Wikipedia

    en.wikipedia.org/wiki/Electret_microphone

    An electret microphone is a microphone whose diaphragm forms a capacitor (historically-termed a condenser) that incorporates an electret. The electret's permanent electric dipole provides a constant charge Q on the capacitor. Sound waves move the diaphragm, changing the capacitance C, which produces a corresponding voltage change across the ...

    en.wikipedia.org/wiki/LM317

    LM317 with heat sink. The LM317 is an adjustable positive linear voltage regulator. It was designed by Bob Dobkin in 1976 while he worked at National Semiconductor. [1] The LM337 is the negative complement to the LM317, which regulates voltages below a reference. It was designed by Bob Pease, who also worked for National Semiconductor.

    Land grid array. LGA 775 on a motherboard. The land grid array (LGA) is a type of surface-mount packaging for integrated circuits (ICs) that is notable for having the pins on the socket (when a socket is used) — as opposed to pins on the integrated circuit, known as a pin grid array (PGA). [1] An LGA can be electrically connected to a printed ...

    en.wikipedia.org/wiki/CAMM_(memory_module)

    CAMM (memory module) Compression Attached Memory Module (CAMM) is a memory module form factor which uses a land grid array, and developed at Dell by engineer Tom Schnell as a replacement for DIMMs and SO-DIMMs which use edge connectors and had been in use for about 25 years. [1] The first SO-DIMMs were introduced by JEDEC in 1997. [2][3][4][5]

  9. Soviet integrated circuit designation - Wikipedia

    en.wikipedia.org/wiki/Soviet_integrated_circuit...

    The soviet integrated circuit designation is an industrial specification for encoding the names of integrated circuits manufactured in the Soviet Union and the Post-Soviet states. 25 years after the dissolution of the Soviet Union, a number of manufacturers in Russia, Belarus, Ukraine, Latvia, and Uzbekistan still use this designation.
