Working Principles

The THS4012CD is a voltage-feedback operational amplifier that amplifies input signals with high speed and low distortion. It utilizes a differential amplifier configuration to amplify the voltage difference between its non-inverting (IN+) and inverting (IN-) inputs. The amplified output signal is then fed back to the inverting input through a feedback resistor, which helps stabilize the gain and overall performance of the amplifier.
