AD8023ARZ

AD8023ARZ is a high current output, triple video amplifier. It is a high current output drive, high voltage output drive, and triple video amplifier. This amplifier has 70mA of output current and is optimized for driving large capacitive loads. It is a current feedback amplifier and features gain flatness of 0.1dB to 10MHz while offering differential gain and phase error of 0.06% and 0.02°. It uses a maximum supply current of 10.0mA per amplifier and runs on ±2.5V to ±7.5V power supply. The outputs of each amplifier swing to within one volt of either supply rail to easily accommodate video signals. It is unique among current feedback opamps by virtue of its large capacitive load drive with a small series resistor, while still achieving rapid settling time. It is used in applications such as LCD displays, video line drivers, broadcast and professional video, computer video plug-in boards, consumer video, and RGB amplifiers in component systems.
