![]() The LM386 is one of the most common amps used in DIY guitar preamplifiers and sustainers due to its ability to run on a single 9V battery.An improved model, "The EasyEDA LM386EE spice model" developed for the simulations of the "Tesseract Guitar Practice Amplifier" project.The original "No-Frills LM386 Model" by Dave Dilatush.JRC devices, marked as 386 JRC, are sometimes misleadingly referred to as the JRC386.Īlthough National Semiconductor and Texas Instruments (who bought National Semiconductor in 2011 ) do not provide an official SPICE model for the LM386, there are two independently developed models freely available: The JRC devices are also available in a single-in-line package. or UTC) as the LM386 and the New Japan Radio Co. There are three different models of the LM386 that have slightly different specifications, outlined below.Īlmost identical versions of the device are available from Unisonic (Unisonic Technologies Co. ![]() 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. It is suitable for battery-powered devices such as radios, guitar amplifiers, and hobby electronics projects. The LM386 is an integrated circuit containing a low-voltage audio power amplifier.
