la4440 amplifier circuit diagram

la4440 amplifier circuit diagram

 La4440 is a stereo Audio amplifier IC. It also can make the bridge for a mono amplifier circuit amplifier board. In dual mode, it gives 6 Watts per channel and in bridge mode, It gives 19 Watts of output. It has good ripple rejection of 46dB, small residual noise, built-in over-voltage and surge voltage protection, etc. ideal feature of the IC is its pin-to-pin protection. Here LA4440 is wired in Stereo configuration using both inputs and outputs. here we can get the la4440 amplifier circuit diagram.

Description of LA4440

• This IC has two channels to use with Mono and Stereo
• Dual mode 6W x 2=12Watts
• Bridge mode 19Watts
• 46 dB Ripple rejection
• Power handling 12V typically. and18V Max.
• Good channel separation and low distortion
• Built-in Audio Muting function and Pin-to-Pin protection
• Surge protection circuitry

 

The diagram

This is the circuit diagram for la4440. here we can see the bridge mode for 19 Watts. 

Component list:

1.Resistor 100K

2.Resistor 680ohm

3.47uf 16volt capacitor

3.47uf 16volt capacitor 

4.100uf 25volt capacitor 

5.100uf 25volt capacitor

6.100uf 25volt capacitor

7.100uf 25volt capacitor 

Here this diagram is the Bridge mode. mono diagram circuit. this mono Bridge circuit can make 19 watts and the Dual mode 6W x 2=12 watts.
you can use 12 volts to a maximum of 18 voltage. but good to use in 12 voltage for its long life. 

LA4440 or 4440 is a dual-channel audio amplifier IC. LA4440 is a monolithic integrated circuit. The LA4440 IC amplifier circuit diagram is given in this article. It is  applicable to two modes,

1. Stereo amplifier mode
2. Bridge amplifier mode.

Here in this article, both modes of the LA4440 IC circuit diagram are explained.
