Working Principles

The INA193AIDBVRG4 is an instrumentation amplifier designed to amplify small differential signals while rejecting common-mode noise. It consists of three operational amplifiers configured in a differential amplifier topology. The input stage provides high common-mode rejection, while the output stage delivers rail-to-rail output swing.

The amplifier operates by amplifying the voltage difference between the positive and negative input pins, while rejecting any voltage that is common to both inputs. This makes it ideal for applications where small differential signals need to be accurately amplified, such as sensor interfaces, medical instrumentation, and industrial control systems.
