Working Principle

The working principle of the AD8079ARZ-REEL operational amplifier is based on a circuit design which utilizes transistors and capacitors. The capacitors are connected between the inputs and outputs of the amplifier, and the transistors act as switches to control current flow. This allows the operational amplifier to function as an amplifier by controlling the flow of current from the amplifying signal.

The input signal is received at the amplifier’s non-inverting input, is amplified by the transistors, and then is output to the circuit’s output. The amplifier can be configured in various ways to adjust the gain of the amplifier and to adjust the operating frequency. The gain of the amplifier is controlled by the ratio of the input resistance to the output resistance.

The current feedback architecture used with the AD8079ARZ-REEL amplifier is designed to achieve a high-speed performance. As the gain of the amplifier is increased, the input resistance is decreased while the output resistance is increased. This allows the amplifier to provide a much higher gain at a higher frequency.
