4440 Double Ic Amplifier Circuit. 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. As in this circuit the input is directly connected to a op amp input decoupling is a must.
The ic has built in thermal over voltage and short circuit protection. It may be in the device s user manual but if not you can get a rough estimate by playing a 60 hz pure sine wave there are apps that will do this at full volume and measuring the ac voltage between ground and the left or right channel with a multi meter. Ideal feature of the ic is its pin to pin protection.
The ic is known for its high power easy availability and cheap price which makes it popular among.
La4440 ic may be a two channel sound amplifier intensifier with inbuilt in double channels. Hope you ll like this video you can give me suggestions to make videos social media links for any query or assistance related to this video message me. As in this circuit the input is directly connected to a op amp input decoupling is a must. This circuit uses an la4440 and some supporting components to give you much more power while retaining a small package that you can use.
