The working principle of ADA4853-2YCPZ-RL Video Amplifier is quite straightforward and is based on the negative feedback topology. The device receives the input differential signal and amplifier it through a two stage inverting amplifier. The inverting amplifier is composed of two current mirrors and performs the basic amplification of the input signal. The non-inverting outputs is fed back to the inverting input via an internal voltage controlled high impedance current limiter. This high impedance current limiter is then used to set the amount of gain that the amplifier will have. This, in turn, sets the output of the amplifier to the desired level, separating the output voltage from the input voltage with defined gain, called the unity gain.

The ADA4853-2YCPZ-RL Video Amplifier is an excellent choice for a wide variety of video applications due to its wide bandwidth, low power consumption, rail-to-rail output, and low input voltage noise.
