Sep 26, 2020 · The model (actually two models Lm386 and Lm386_) is in the Lm386.sub file in the SUB folder. In the folder ...Documents\LTspiceXVII\lib\sym\ZZZ\Sound_Amplifiers is the …

Dec 4, 2024 · It looks as though you are using the first two LM386's to boost gain. This is wasteful because you and obtain as much or more gain using something like and LM358 (dual op amp) …

Mar 26, 2009 · Hi all, I manage that the Multisim in our college doesnt have the LM386 component. As i know we can create a component by our own in Multisim. Can anyone here …

Feb 28, 2016 · I m sending screenshots of the LTSpice simulation. The bottom screens (lm386-testv01.PNG and lm386-testv01-graphic.PNG) are for the transient analysis and the lm386 …

Oct 3, 2022 · The datasheet of the LM386 shows a graph of peak-to-peak output voltage into speakers that are 4, 8, 16 ohms and infinity at supply voltages from 4V to 12V. With a 6V …

Mar 18, 2021 · I've been playing with the LM386 for a couple days. I've tried various different schematics online. If I plug the output of the LM386 into any raw speaker or amplified system, I …

Sep 18, 2007 · In the LM386 schematic, let Rf be the resistor between pins 1 and 5. Let Rs be the resistance between the emitters of the diff amp (this is 1.5k, or 150 ohms if there is a cap …

Mar 17, 2019 · I am looking for a npn or pnp transistor substitute for the Lm 386 amplifier chip which powers a 8 ohm 1/2 watt speaker. The reason that I want to make this switch is for cost, …

May 12, 2020 · LM386 is an output amplifier, not a preamp. You should be using an opamp for the preamp stage. LM386 is a low power audio amplifier that can only output about ¼W. You are …

Oct 10, 2020 · Its author did not look at the datasheet for the LM386 and did not lookup an electret mic in Google. 1) The electret mic MUST be powered with a resistor from a filtered DC …
