Working Principles

The INN2214K is an operational amplifier that amplifies and conditions input signals. It operates based on the principles of differential amplification and feedback control. The non-inverting input receives the input signal, while the inverting input provides a reference voltage. The amplifier amplifies the difference between these two inputs and produces an output signal. The gain, bandwidth, and other characteristics are determined by the internal circuitry and external components.
