What class of amplifier is the LM386?
Class-AB audio amplifier
700-mW, mono, 5- to 18-V, analog input Class-AB audio amplifier.
What is LM386 audio amplifier?
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.
Why do audio speakers have different ratings?
All speakers have an impedance rating in ohms, which represents how difficult the speaker is to power. The lower the impedance, the more efficiently it allows the electric signal, which is basically the music, to pass through the speaker.
What is the difference between Class ABCD amplifiers?
Less-than-highest fidelity. After amplification, a low-pass filter smooths the output signal so the amp won’t put out pulses of power but rather, a continuous analog power output. It also removes the interference generated by those high-frequency DC pulses.
What is LM386 power amplifier?
LM386 is a low voltage power amplifier with an inactive power draw of 24mW, which makes it suitable for battery controlled applications. The most common package for LM386 is an 8 – pin DIP.
What is the equivalent IC of the LM386?
LM386 Equivalent IC. LM380 . Alternatives Audio Amplifiers. LM4871, AD620, IC6283, JRC4558, Where to use the LM386 Audio Amplifier. The LM386 is a low power audio frequency amplifier which is very commonly used in small audio amplifiers. The IC consumes very less power and hence can be operated using a 9V battery easily. It can easily drive an
What is the function of each pin in LM386?
From the pin diagram, it is clear that LM386 is a simple Amplifier IC with possibly minimum external connections. The following table shows the functions of each pin in the LM386 Amplifier IC. Pins 1 and 8 are Gain Control Pins.
What is the gain and voltage gain of LM386?
The gain range is 20 to 200, gain is internally set to 20 (without using external component) but can be increased to 200 by using resistor and capacitor between PIN 1 and 8, or just with a capacitor. Voltage gain simply means that Voltage out is 200 times the Voltage IN. LM386 has a wide supply voltage range 4-12v.
