What can replace LM386?

LM4862 Amplifier Circuit – A Better LM386 Alternative.

Can I use LM386 instead of LM358?

#1745. There’s no way. Do not just consider similar part numbers. LM358 is a BJT based op-amp as Ray mentioned, with mirror current drivers so it can run on double power supplies (+Vcc and -Vee) while LM386 is only single supply.

Which IC is used in audio amplifier?

The IC LM386 is the most important integrated circuit used in the audio section, and it is commonly used in the following applications.

What class of amplifier is the LM386?

Class-AB audio amplifier
700-mW, mono, 5- to 18-V, analog input Class-AB audio amplifier.

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.

Is 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 is an audio amplifier circuit?

The circuit of the audio amplifier consists of a transistor a device to apply the input signals and a speaker at the output. The transistors are connected based on the necessity. The important factors that need to be considered while designing a audio amplifier is gain,noise, frequency response and distortion.

What is LM386 audio amplifier?

The Audio Amplifier using LM386 is a low power circuit that can deliver a maximum power of 1 Watt (1W) and can be used in a wide range of applications like portable speakers, laptop speakers, etc.

Is LM386 an op-amp?

Is LM386 an opamp?

How does the LM386 amplifier work?

They take an input potential (voltage) and produce an output potential that’s tens, hundreds, or thousands of times the magnitude of the input potential. In an amplifier circuit, the LM386 takes an audio input signal and increases its potential anywhere from 20 to 200 times.

How many inputs does the LM386 have?

The LM386 has two inputs, an inverting input, and a non-inverting input. This is common for operational amplifiers and other small amplifier designs, but not generally seen on power amplifiers. In many amplifier circuits, one of the inputs is unused, but the design retains both for versatility.

Why does the LM386 have a dual rail power supply?

This is why many amplifiers have a dual rail power supply, with a negative rail, a positive rail, and 0V in the middle. The LM386, and other single-rail amplifiers are designed so that the middle of the waveform sits at the half-way point between the positive supply rail, and ground.

Which one is better LM386 or lm380?

Before jumping into specifics, when I started into the Lm380 is much better than lm386..it has higher wattage…you can go for the tda series from st microelectronics…but many of those tda series has been discontinued and few can be available…a high end ic is available from national semi is the lm3886 and lm1875

Is it possible to overdrive the LM386?

While overdriving amplifiers is sometimes desirable to musicians, and guitarists in particular, it would make for an interesting experiment with the LM386! Frequency response for the LM386 is fairly flat until after 20kHz. As noted earlier, most of us can’t hear this high anyway.
