Working Principles

CP3155B is an operational amplifier that amplifies and processes input signals. It consists of multiple transistors and passive components integrated into a single IC package. The amplifier operates by applying the input signal to the non-inverting input terminal and comparing it with the inverting input terminal. The amplified output signal is then obtained at the output pin.
