Working Principles

The INA2132U/2K5 is an instrumentation amplifier that amplifies small differential signals with high accuracy. It consists of a differential input stage, a gain stage, and an output stage. The differential input stage amplifies the voltage difference between the non-inverting (IN+) and inverting (IN-) inputs. The gain stage provides adjustable gain to the amplified signal, while the output stage buffers and drives the output signal.
