Amplifier circuit using LA4440 IC

Hello, readers welcome to the new post. We will discuss the Amplifier circuit using LA4440 IC. The amplifiers are circuits that are used in electronic projects to convert the low-power input single to high-power signals. The output of the amplifier has features such as less noise, non-distorted, and higher quality than the input. There are different types of configurations of amplifiers designed here we will use LA4440 amplifier circuits to make the audio amplifier circuits.

The LA4440 has two audio channel configurations with a dual channel built. It comes in applications such as bridge circuits. Before making this circuit you must have the breadboard assembly of this project to find the correct design and configuration. After that, it is practically designed over the PCB.

Introduction to LA4440 IC

LM4440 is a dual-channel audio amplifier integrated circuit that has a dual-channel configuration and is used for bridge amplifier circuits.
It has two modes dual mode provides six watts of power in a single channel and for the bridge, the configuration has nineteen watts of power
This IC comes with a fine rejection ripple having the value of sixty-six decibels less residual noise, with employed for surge volts protection

Its main feature that helps to use for projects is pin-to-pin protection
Its common uses are in home automation, vehicle amplifier circuits, and applications where input volts is twelve volts
The boards offered a good thermal and electrical configuration so can be used for conditions where high temperatures is involved.
It is used for bass amplifier arrangements to offer good quality sound having a decent signal frequency
for bridge configuration of this IC has 19-watt power. So use four ohms to eight-ohm speakers.

Project Components

The components used for projects are explained here
LA4440: It is the main component of our projects that will be used to amplify our input given
Potentiometer for resistance changes. It has two static points and one slider. Sidler changes the resistances of these components according to circuit requirements
Battery: We are using the 12 volts battery mostly this value of the battery is used at the input to make a good design configuration
Pin connectors: Here we are using 2 and 3-pin connector configurations to join the different components.
capacitors: Polyester and other conventional capacitors of required capacitance have been used.
Resistors: Resistors are used for creating the current limiting circuits and also do the filtering process of circuits
The circuit diagram for the audio amplifier is designed below. Here capacitors are denoted as C0 which is at the output side used for the reduction of ripples existing in the volts. There must be a value of capacitor Cx and Cz of about 100 microFarad if not for this value an output having less frequency will generated.
Here keep in mind that the pinout of the LA4440 is working for stereo amplifier function and bridge, the function will be connected to the ground.

The capacitors denoted as Cr and Ct are employed for the elimination of oscillations while resistance Rx and Ry work as filtering resistances. For stereo and bridge volts value can be provided up to 18 volts but try to make it 12 volts that we have in this project

Applications

The common applications of these circuits are mentioned here
