Working Principles

The NR111E is an operational amplifier that amplifies and conditions input signals. It operates based on the principles of differential amplification and negative feedback. The non-inverting input receives the input signal, while the inverting input provides a reference voltage. The difference between these inputs is amplified by the internal circuitry and delivered at the output pin. Negative feedback is used to stabilize the amplifier's gain and reduce distortion.
