Hey there im a student at chisholm catholic college and am working on an engineering project. It has good ripple rejection of 46db, small residual noise, builtin overvoltage, and surge voltage protection, etc. Just wondering if you have a diagram of a circuit for a 100 watt sub woofer amplifier that can run off 12 volts. This la4440 amplifier ic is most suitable for low power audio applications, it has good ripple rejection as 46db and has good channel separation. La4440 ic is a two channel audio amplifier with inbuilt in dual channels.
It is 12 volts audio amplifier using is lm4440 ic 19 watts amplifier. Simple amplifier circuit19 watts using la4440 ic from sanyo. Because of the highpower nature of the circuit, it is not recommended to used a breadboard to build this circuit. Hence, we will be building a pcb at home by designing an audio amplifier pcb for this circuit. La4440 is a two channel audio power amplifier ic with inbuilt in dual channels enables it for stereo and bridge amplifier applications. In dual mode it gives 6 w per channel and in bridge mode 19 w output. The audio amplifier ic la4440 cd4440 tda4440 is the most using ic for stereo audio amplifier circuit such as audio player,dvd player etc. This ic amplifier has 2 modes stereo amplifier and bridge. We have designed it without pcb and used few capacitors with it.
It uses very fewer components other than the ic la4440. La4440 power amplifier, 6 w 2channel, bridge 19 w typ. La4440 ic audio amplifier circuit diagram and pcb layout. Many power amplifier circuit diagram with pcb layout.
