What is the most common signal to be amplified in an amplifier?
The common emitter (or common source, common cathode, etc.) is most often configured to provide amplification of a voltage applied between base and emitter, and the output signal taken between collector and emitter is inverted, relative to the input.
How does the LM386 work?
The IC LM386 is a low-power audio amplifier, and it utilizes low power supply like batteries in electrical and electronic circuits. When this amplifier uses a 6V power supply for the operation then the static power drain will be 24 milliwatts to make the amplifier for an ultimate operation of the battery.
Can a LM386 audio amplifier power a speaker?
It is a very low cost audio amplifier and can power any speaker. For the cost and size of the circuit, the sound from the LM386 Audio Amplifier can be adequately loud. There are many Audio Amplifier Circuits designed using LM386 IC. The main problem with these circuits is noise and interference.
What kind of input does the LM386 have?
This is exactly what’s happening in this month’s Kids’ Basics project. 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.
How many times does a LM386 increase the potential?
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.
What is the harmonic distortion of the LM386?
The lowest Total Harmonic Distortion of the LM386 is 0.2%, somewhere between 500 and 1000Hz. The curve starts at 20Hz, with 0.5%, which is reached again at 5kHz. After this, THD rises all the way to 1.5% at 20kHz.
