To understand the working principle of ADA4432-1BCPZ-R2, we need to look at the classic operation of linear video amplifiers. The key component in a linear video amplifier is an operational amplifier. The input signal is first applied to the non-inverting input of the amplifier, and then passes through the feedback network to the inverting input. The output voltage is determined by the difference between the two.

The feedback network can be either a voltage divider, or an active circuit with an amplifier. The active feedback device provides an increased gain and a decreased output impedance, and allows the amplifier more accurately track the input. The gain of the amplifier is determined by the ratio of resistances in the feedback network.

On the other hand, ADA4432-1BCPZ-R2 makes use of a differential amplifier in order to amplify the input signal. A differential amplifier is an operational amplifier that amplifies the differential input signal while rejecting the common-mode signal. This allows it to achieve higher linearity and better performance. Additionally, it has a wider input dynamic range, a higher output current, and a better overall aberration performance than single-ended amplifiers.

Overall, ADA4432-1BCPZ-R2 is a high precision, low power, low noise linear video amplifier that can provide a high output current and fast settling time for applications that require high speed, ultralow noise, and low distortion performance. It is suitable for driving displays such as LED, LCD, and OLED panels and is used in consumer electronics, automotive, aviation, and industrial applications. The device makes use of a differential amplifier with an active feedback network in order to achieve higher linearity and better performance.
