Working Principles

The OPA373AIDRG4 is a voltage-feedback operational amplifier designed for precision signal amplification and conditioning. It operates by amplifying the difference between the voltage at its non-inverting input (IN+) and inverting input (IN-). The amplified output is then provided at the OUT pin. The amplifier maintains high gain accuracy, low distortion, and low noise throughout its operating range.
