PRODUCT DESCRIPTION
each amplifier in order to power down the amplifier or high The AD8023 is a high current output drive, high voltage output impedance the output. This can then be used in video multi- drive, triple video amplifier. Each amplifier has 70 mA of output plexing applications. The AD8023 is available in the indus- current and is optimized for driving large capacitive loads. The trial temperature range of –40°C to +85°C. amplifiers are current feedback amplifiers and feature gain flatness of 0.1 dB to 10 MHz while offering differential gain and phase error of 0.06% and 0.02°.
