Linear - Amplifiers - Video Amps and Modules

The AD8073JRZ-REEL7 is a low distortion, high speed, current feedback video amplifier with a gain of +2. It is optimized for performance in data and video transmission applications. The device has a wide gain bandwidth (200 MHz) and excellent low distortion performance (typically –65 dBc at 1 MHz) that make it ideal for wide bandwidth video transmission systems.

The device features excellent common-mode rejection (CMV) performance, fast settling time (250 ns) and low power dissipation (typically ≈310 mW/amplifier at 5V) making it ideal for video applications where power dissipation is a major concern. The gain of the AD8073JRZ-REEL7 is set externally through an external resistor, or it can be adjusted with a digital potentiometer to up to a gain of +2. The output of the device can be adjusted through a simple control method so that the device will have a wide range of output levels.

Operation principle

The AD8073JRZ-REEL7 operates on the principle of current feedback amplification. This type of amplifier operates by sensing the current flowing through the device and then amplifying the current instead of amplifying the voltage. This has several advantages, such as improving the overall gain accuracy, reducing distortion in the signal, and improving the stability of the device over temperature and supply variations.

Unlike a voltage feedback amplifier, a current feedback amplifier can handle voltage levels up to the supply voltage of the device. This means the amplifier will not be limited by the maximum output voltage limitation of a voltage feedback amplifier.

Applications

The AD8073JRZ-REEL7 is ideal for applications ranging from analog-to-digital and digital-to-analog conversions, as well as applications requiring high resolution of low frequency signals. The device can also be used in high speed imaging and high speed line scan applications, where high gain and low distortion are required.

The device can also be used for video encoding and decoding, as well as video and line scan applications, where high gain and low distortion are required. The device is also well suited for video camera, network video, datacom and industrial imaging applications.

Conclusion

The AD8073JRZ-REEL7 is a high performance low distortion current feedback video amplifier with a wide gain bandwidth (200 MHz) and excellent low distortion performance (typically –65 dBc at 1 MHz). The device features excellent common-mode rejection (CMV) performance, fast settling time (250 ns) and low power dissipation (typically ≈310 mW/amplifier at 5V). The gain of the AD8073JRZ-REEL7 can be adjustable through external resistors or a digital potentiometer, and the output can be adjusted through a simple control method. The device has a wide range of applications, such as analog-to-digital and digital-to-analog conversions, high speed imaging and high speed line scan applications, video encoding and decoding, and video and line scan applications.
