Lm386 Ic

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.

How does LM386 circuit work?

The LM386 is a type of operational amplifier (Op-Amp). In an amplifier circuit, the LM386 takes an audio input signal and increases its potential anywhere from 20 to 200 times. That amplification is what's known as the voltage gain.

What can replace LM386?

Some alternative ICs you can use are LM380, TDA2822M, NJM2073 and MC34119.

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.

Why is LM386 used?

The LM386M-1 and LM386MX-1 are power amplifiers designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200.

What are the 3 types of amplifiers?

Classification of the amplifier can be done in 3 different ways. Voltage amplifiers. Current amplifiers. Power amplifiers.

What is LM358 IC?

LM358 IC is a dual operational amplifier integrated circuit with two Op-Amp powered by a common power supply. It consists of two independent compensated operational amplifiers with low power and high gain frequency. LM358 is specially designed to operate from a single supply over a wide range of voltage.

Which IC used in speaker?

It is mostly used as an amplifier in computer speakers and small portable stereos. The LM386 IC is available in 8 pins dual in-line package (DIP-8). The voltage gain of the amplifier can be adjusted to 20 and it will be enhanced to 200 by adding external components like resistor and capacitor among the pin 1 and 8.

What class 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 is bypass pin in LM386?

talking about the LM386's infamous 'Bypass' pin (pin 7). It seems that this pin is often left unused, and I see no end of speculation regarding its intended purpose. In simplest terms, it allows the experimenter an easy way to filter the voltage feeding the differential input stage.

How good is the LM386?

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.

Why LM358 IC is used?

LM358 can be used as transducer amplifier, DC gain block etc. It has large dc voltage gain of 100dB. This IC can be operated on wide range of power supply from 3V to 32V for single power supply or from ±1.5V to ±16V for dual power supply and it also support large output voltage swing.

Which IC can be used instead of LM358?

I will consider lM158, LM2904 and TL082. I have also found 2 more alternate ICs for LM358 with same pinouts and my requirements.

How does audio IC work?

A sound chip is an integrated circuit (chip) designed to produce audio signals through digital, analog or mixed-mode electronics. Sound chips are typically fabricated on metal–oxide–semiconductor (MOS) mixed-signal chips that process audio signals (analog and digital signals, for both analog and digital data).

How do you set a gain in LM386?

To make the LM386 a more versatile amplifier, two pins (1 and 8) are provided for gain control. With pins 1 and 8 open the 1.35 kΩ resistor sets the gain at 20 (26 dB). If a capacitor is put from pin 1 to 8, bypassing the 1.35 kΩ resistor, the gain will go up to 200 (46 dB).

Which IC we use in audio amplifier circuit?

LM386 is already one of the important IC in audio department and is featured commonly portable speakers and laptop speakers. The LM386 Audio Amplifier Circuit can be used for recording voice from microphone, building small speakers that are battery operated, in FM Radio Devices, etc.

Which type of amplifier is best?

Class “A” amplifiers are considered the best class of amplifier design due mainly to their excellent linearity, high gain and low signal distortion levels when designed correctly.

Who uses 3rd power amps?

But the list of acts using 3rd Power amps is impressive; Besides Kravitz, it includes The Who, Little Big Town, Kenny Chesney, Dierks Bentley, Joe Walsh, Steve Miller, Anderson East, Mona, The Wild Feathers, and Jason Isbell, to name just a few.

Is LM358 a good op-amp?

LM358 IC can also be used as transducer standard operational amplifier and it is suitable for our needs. It can handle voltage from 3V to 32V DC supply and current up to 20mA per channel. It consists of 8 pins which contains two operational amplifiers.
