LM3886 Amplifier

This tutorial is an introduction to LM3886 amplifiers, the most basic building block of op-amps. This circuit is a simple amplifier that can be used as a basis for more complicated amplifier designs. The circuit uses one LM3886, which is an adjustable gain amplifier with a quiescent current of around 100nA. This means that the current used to power the circuit when it is idle is less than 100nA. This is a good starting point for more complicated amplifier circuits. The circuit uses two resistors to set the gain of the amplifier.


LM3886 Audio Power Amplifier

LM3886 Amplifier Circuit Diagram

The audio power amplifier is an important part of the sound system. The LM 3886 IC audio power amplifier with an audio power amplifier unit is very powerful and capable of producing 68 watts of 2  4 Ohm load power and is capable of delivering 38 W power with an 8-ohm load produce. With a well-placed sound of 20Hz-20kHz, playback is also included in the LM3886 audio power amplifier.

The LM3886 audio power amplifier is equipped with surge protection, which protects the output circuit from over-voltage, under-voltage, overload, power supply, and maximum runaway dad thermal temperature. The LM3886 audio power amplifier also has a noise cancellation system that keeps sound away from the noise.
