4440 Amplifier Circuit. It has out class ripple rejection of 46db built in over voltage and surge voltage protection and deca 300 many more. This ic amplifier has 2 modes stereo amplifier and bridge amplifier mode according to datasheet it has following features built in 2 channels dual enabling use in stereo and bridge amplifier applications.
La4440 or cd4440 is a dual channel audio monolithic amplifier integrated circuit. In dual mode it gives 6 w per channel and in bridge mode 19 w output. If you are listening to music or movies on laptops and computers this is a useful little project for you.
Laptop speakers are never loud enough to give satisfying listening.
La4440 is a two channel audio power amplifier ic with inbuilt in dual channels enables it for stereo and bridge amplifier applications. Right now are visiting constructed a simple ic 4440 intensifier or an amplifier circuit yet the yield is extremely decent and high. A simple audio amplifier based on the la4440 ic. The circuit will have two ls4440 amplifiers ics and will be able to drive two 20w speakers 20w 20w with volume bass and treble control.
