The Easy to Use outputs of each amplifier swing to within one volt of either 200 mA Short Circuit Current supply rail to easily accommodate video signals. The AD8023 Output Swing to 1 V of Rails is unique among current feedback op amps by virtue of its large APPLICATIONS capacitive load drive with a small series resistor, while still LCD Displays achieving rapid settling time. For instance, it can settle to 0.1% in Video Line Driver 35 ns while driving 300 pF capacitance. Broadcast and Professional Video The bandwidth of 250 MHz along with a 1200 V/ s slew rate Computer Video Plug-In Boards make the AD8023 useful in high speed applications requiring Consumer Video a single +5 V or dual power supplies up to 7.5 V. Further- RGB Amplifier in Component Systems more, the AD8023 contains a high speed disable function for each amplifier in order to power down the amplifier or high PRODUCT DESCRIPTION impedance the output. This can then be used in video multi- The AD8023 is a high current output drive, high voltage output plexing applications. The AD8023 is available in the indus- drive, triple video amplifier. Each amplifier has 70 mA of output trial temperature range of 40C to +85C. current and is optimized for driving large capacitive loads. The 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. V V IN IN V O V O Figure 2.
