Working Principle

The OPA347UA is an integrated circuit with a single amplifier stage. It is powered by a 5V to ±11V supply. The amplifier has two inputs, the non-inverting input (+) and the inverting input (-). In between these inputs is a feedback network, which determines the gain of the amplifier. The amplifier is designed to have a unity gain (1V/V) when the two inputs are connected together. The amplifier produces an output voltage that is the product of the two inputs (Vin * gain). The output voltage can be adjusted with an external resistor or capacitor. The amplifier also includes an internal buffer stage which can be used to drive low impedance loads.
