What is IC LM386?

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.

What is inside LM386?

The Audio amplifier can be built with LM386 IC, capacitors like 100 µF, 1000 µF, 0.05 µF, 10 µF, Potentiometer – 10 KΩ, resistor-10 KΩ, power supply-12V, speaker-4Ω, breadboard, and connecting wires. Basically, this Audio Amplifier includes 3-functional blocks such as Power as well as Output, Bypass, gain control.

What 3 packages Does the Texas Instruments LM386 come in?

LM386. LM386.

  • LM386. UNIT.
  • D (SOIC) DGK (VSSOP)
  • P (PDIP)

    • How does the LM386 work?

    LM386 is a 8 pin Power amplifier IC suited for low power applications. It has a wide supply range from 4v to 12v and capable of providing voltage gain from 20 to 200. The output gain is internally set to 20 to reduce the usage of external parts and can be modified using two pins of the IC.

    What is the use of LM386 audio amplifier?

    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. They can also be used in TV Sound Systems, Line Drivers, Servo Drivers, Ultrasonic Drivers, etc.

    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.

    What class amp is the LM386?

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

    What speakers work with LM386?

    Speaker impedance: The LM386 was primarily designed for a 4Ω speaker load, but is rated for 8Ω and 32Ω loads as well. Distortion: Under ideal conditions, 0.2% total harmonic distortion (THD) when driven with 6V of power into an 8Ω speaker at low power ratings, and up to ~10% THD closer to maximum power.

    Why we use LM386 in 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….Introduction to LM386.

    What is a 8 ohm speaker?

    8 ohm speakers are used typically for home stereo systems, outdoor systems, and musical instrument amplifiers. Because home stereos have access to higher power supply voltages, a higher impedance speaker can be used to power speakers than say in a car. 4 ohm speakers are typically used for car stereo systems.
