Working Principles

The HI7190IBZ-T is a voltage feedback operational amplifier that amplifies and conditions electrical signals. It operates by taking the difference between the non-inverting input (IN+) and the inverting input (IN-) and amplifying this differential voltage with a high gain. The amplified signal is then available at the output pin (OUT). The amplifier is powered by a positive power supply (V+) and a negative power supply (V-), and the ground (GND) reference completes the circuit.
