The AD8072JRZ is an extremely versatile, low noise, high performance, wideband amplifier. It boasts a specially designed amplifier using bipolar transistors for improved power efficiency and superior frequency response characteristics. It is used in applications such as low power video amplifiers, audio amplifiers, and imaging amplifiers. The AD8072JRZ is a linear type amplifier, specifically designed for video amps and modules.

The AD8072JRZ has a versatile power supply range, ranging from +2.7V to -1.6V, with a quiescent power supply current of only 10uA, making it well suited for low power applications. It features an extremely high gain bandwidth product of 20MHz and offers an excellent signal-to-noise ratio for improved system performance. The AD8072JRZ has an incredible common-mode rejection ratio of 80dB at 10MHz, allowing it to reject unwanted signals from outside sources.

The AD8072JRZ has a low input offset voltage of only 12uV at room temperature, and its minimum slew rate is 55V/us, making it well suited for fast, dynamic signal applications. The AD8072JRZ can also be used in a wide range of frequencies, ranging from 10MHz to 500MHz. In summary, the AD8072JRZ is an excellent choice for video amp and module design.

The operating principle of the AD8072JRZ is based on a simple bridged connection, which is used to drive the output to the desired voltage. The amplifier is composed of a feedback network, a transconductance amplifier circuit, an output stage, and the power supply connections. The feedback network consists of a series of resistors which act as the gain setting for the amplifier. The bridge arrangement allows for two outputs, with each output being driven independently. The transconductance amplifier controls the gain of the amplifier by changing the gain of the signal in the feedback network.

The output stage is composed of two transistors, one of which is connected to the signal input and the other to the feedback network. The two transistors are biased in order to achieve the desired output. The power supply connections are used to supply power to the amplifier, and, depending on which supply voltage is used, the output performance of the amplifier will vary accordingly. When the amplifier is turned on, the signal is amplified until it reaches the desired output level.

The AD8072JRZ is ideal for low power video and audio applications due to its low power consumption and wide dynamic range. It is an excellent choice for video amps and modules, offering extreme performance with very impressive signal-to-noise ratio, wide bandwidth, and good common-mode rejection ratio. The high gain and low noise characteristics allow the amplifier to be used for both low-noise and high-power applications, making it a truly versatile amplifier.
