AD8023:  High Current Output, Triple Video Amplifier

Product Description

The AD8023 is a high current output drive, high voltage output drive, triple video amplifier. Each amplifier has 70 mA of output 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°.

The AD8023 uses maximum supply current of 10.0 mA per amplifier and runs on ±2.5 V to ±7.5 V power supply. The outputs of each amplifier swing to within one volt of either supply rail to easily accommodate video signals. The AD8023 is unique among current feedback op amps by virtue of its large capacitive load drive with a small series resistor, while still achieving rapid settling time. For instance, it can settle to 0.1% in 35 ns while driving 300 pF capacitance.

The bandwidth of 250 MHz along with a 1200 V/µs slew rate make the AD8023 useful in high speed applications requiring a single +5 V or dual power supplies up to ±7.5 V. Furthermore, the AD8023 contains a high speed disable function for each amplifier in order to power down the amplifier or high impedance the output. This can then be used in video multi-plexing applications. The AD8023 is available in the industrial temperature range of -40°C to +85°C.
