LF353 Dual BiFET Op Amp

Contents hide

The LF353 is a Dual BiFET operational amplifier. The IC is constructed using the state of the art analog electronic technologies, laid out on a single monolithic integrated circuit. The IC is always available in an 8 – pin hermetically sealed SO-8 dual in line packaging (DIP). LF353 op-amp is available only in dual operational configuration. The IC offers a wide variety of features such as high noise immunity, excellent thermals, and ESD protection.

BiFET Operational Amplifier

BiFET (Bi – directional field effect transistor) operational amplifier is a simple electronic configuration that boosts up a voltage of lower strength to a higher level. Operational amplifiers are usually designed to be used with external feedback components such as resistors and capacitors. Operational amplifiers are commonly used in devices such as home theatre systems, VCRs, PCs, Laptops, etc.
