CA3401 Quad Operational Amplifier

Contents hide

CA3401 consists of 4 high gain operational amplifiers, which are operated using a single power supply. The IC is always available in a 14-pin hermetically sealed dual in line package (DIP), which makes it really easy to interface and use with other PMOS, NMOS, and CMOS devices. CA3401 offers a wide variety of features such as wide unity gain bandwidth, high noise immunity, and ESD protection. The IC is well suited in applications pertaining to the automotive industry, industrial control systems, and general purpose amplifiers. It is also used in devices such as oscillators, tachometers, and active filters.

Operational Amplifier

An operational amplifier is a voltage amplifying device; that is designed with the intention to be used with external feedback components such as resistors and capacitors between its I/O terminals. These feedback components determine the resulting function or “operation” of the amplifier and by virtue of the different feedback configurations whether resistive, capacitive, or both.
