What is IC LM 386?
The IC LM386 is a low-power audio amplifier, and it utilizes low power supply like batteries in electrical and electronic circuits. This amplifier consists of 8-pins where pin-1 and pin-8 are gain control pins of the amplifier, and this IC is most widely used IC that allows a customer to increase volume.
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.
How does a LM386 audio amplifier work?
Working of LM386 Audio Amplifier Circuit The working of the circuit is very straight forward as all the work is done by the LM386 IC itself. When the system is powered on and proper audio input is given at the input, the LM386 Amplifier the input signal by a factor of 200 and drives the output speaker.
How many watts is LM386?
700-mW, mono, 5- to 18-V, analog input Class-AB audio amplifier.
What is a LM386 power amp?
The LM386 is an integrated circuit containing a low-voltage audio power amplifier. It is suitable for battery-powered devices such as radios, guitar amplifiers, and hobby electronics projects.
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.
How many types of IC amplifiers are there?
Although amplifiers are sometimes classified according to input and output parameters (we’ll get to that), there are 4 basic types, which are: Current Amplifier: As the name suggests, an amplifier that makes the given input current higher. It is characterized by a low input impedance and high output impedance.
Which is the best class of amplifier?
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.
