Working Principles

The THS4121IDGN is a voltage-feedback operational amplifier that amplifies input signals with high speed and low noise. It operates by receiving an input signal at the non-inverting input pin (IN+) and comparing it with the inverting input pin (IN-). The amplified output signal is then provided at the OUT pin. The amplifier requires a positive and negative power supply to operate effectively.
