LM2904 Description

LM2904 is a dual operatioal amplifier. It has two built-in internal amplifiers, specially designed to operate with a single power supply. They can also be operated from divided power supplies. It normally operates on a 3.3V power supply, which is the most common supply for digital systems. LM2904 has different features that make it more efficient and popular on the market. These features include large ranges of power supply, wide bandwidth, etc. We can use LM-2904 while designing active filters, transducer amplifiers, DC blocks, etc.

Where to Use LM2904

The LM2904 is a dual package version of the commonly used LM741 Op-Amp, both of which have the same electrical characteristics. This Op-Amp does not have a latch-up problem and is therefore ideal for use in voltage follower applications. It also has built-in internal frequency compensation and short-circuit protection and therefore requires a minimum number of components to be ready for use. These ICs are commonly found inside DVD players and guitar amplifiers due to these characteristics.

 

LM2904 IC consumes very low current. So if you're looking for an Op-amp IC with all of these features, this IC might be the right choice for you.
