Working Principles

The OP293ES is an operational amplifier that amplifies the difference between its two input voltages. It consists of multiple transistors and resistors configured in a way that allows for high gain and precise amplification. The amplifier operates by comparing the voltage at its non-inverting input (IN+) with the voltage at its inverting input (IN-), and producing an output voltage proportional to the difference between the two inputs.
