Working Principles

The EL9214IREZ is a voltage-feedback operational amplifier that amplifies and conditions electrical signals. It operates by applying the input signal to the non-inverting (IN+) and inverting (IN-) inputs, and amplifying the difference between these inputs. The amplified signal is then available at the output pin (OUT). The amplifier requires a positive supply voltage (VCC) and a negative supply voltage (VEE) for proper operation.
