Why we use LM386 for audio amplifier?
Why we use LM386 for audio amplifier?
LM386 IC has been in use for decades and is still being used as Amplifier in Computer speakers and Portable Stereos. From the pin diagram, it is clear that LM386 is a simple Amplifier IC with possibly minimum external connections….Introduction to LM386.
| Pin Number | Pin Name | Function |
|---|---|---|
| 8 | Gain | Gain Setting Pin |
Can I use LM386 instead of LM358?
They’re not interchangeable. LM386 is an audio amp, intended to drive a speaker. It’s not any kind of opamp like the LM358 is. Never use the LM358 for audio.
How many watts is LM386?
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.
Is the LM386 an op-amp?
The LM386 is an operational amplifier than has been specifically designed for use in audio applications… which means its performance is based on the assumption that it will be driving speakers. At least at some point. However it can, like most other basic audio amplifier chips, be used as a regular op-amp as well.
What can replace LM386?
Some alternative ICs you can use are LM380, TDA2822M, NJM2073 and MC34119.
Is LM386 any good?
The LM386 is a well-designed, basic workhorse that does a decent job when its hooves are kept clean and it’s well-fed. Aside from having a slow op-amp stage by today’s standards, it has decent performance. It can also sound horrible if you neglect it.
What can I use instead of LM386?
LM4862 Amplifier Circuit – A Better LM386 Alternative.
What class of AMP is LM386?
3 LM386 Output Stage: It is a class AB power amplifier, that is to say, a push-pull configuration where each transistor amplifies its corresponding half wave.

What class is LM386?
Which IC is used in audio amplifier?
Where are Audio Amplifier ICs used? Audio amplifier ICs are used in a range of commercial applications. They are found in car stereos, headphones, televisions, keyboards, and toys. They are also used in electronic circuits for line drivers, ultrasonic drivers, power converters and radio amplifiers.
How does LM386 circuit work?
LM386 is a 8 pin Power amplifier IC suited for low power applications. It has a wide supply range from 4v to 12v and capable of providing voltage gain from 20 to 200. The output gain is internally set to 20 to reduce the usage of external parts and can be modified using two pins of the IC.
Can any transistor work as an audio amplifier?
From the above information, finally, we can conclude that a transistor can perform like an amplifier only when it is biased properly. There are several parameters for a good transistor which includes high gain, high bandwidth, high slew rate, high linearity, high i/p impedance, high efficiency, and high stability etc.
Which transistor is used in audio amplifier?
Since the 1970s, most modern audio amplifiers are based on solid-state transistors, especially the bipolar junction transistor (BJT) and the metal–oxide–semiconductor field-effect transistor (MOSFET).
How do you make A simple audio amplifier with one transistor?
Circuting :
- First place transistor on breadboard .
- Insert resistor at pin 1 and 2 of transistor .
- Insert positive terminal of capacitor at pin1 of transistor .
- Insert one wire of 3.5 mm jack at negative terminal of capacitor.
- Insert remain wire of 3.5 mm jack at pin3.
- Insert one wire of speaker at pin2 .
How much voltage is needed to turn on a transistor?
around 0.6V
In reality, we need a non-zero forward voltage drop (abbreviated either Vth, Vγ, or Vd) from base to emitter (VBE) to “turn on” the transistor. Usually this voltage is usually around 0.6V.
