4440 Amplifier Wiring. The la4440 is a very popular dual channel audio amplifier commonly used to build high power audio amplifiers. The ic also incorporates an audio muting function but that is not used here.
Here ic la 4440 is wired as a bridge amplifier to deliver a 19 w rms on a 4 ohm speaker. The ic is known for its high power easy availability and cheap price which makes it popular among home theatre and car amplifier systems which operate on 12v. The ic also incorporates an audio muting function but that is not used here.
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.
The ic has built in thermal over voltage and short circuit protection. La4440 or cd4440 is a dual channel audio monolithic amplifier integrated circuit. The main reasons for using la4440 is small pop noise at the time of power supply on off and good starting balance. 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.
