The AD8072 current feedback amplifiers intended for high volume, cost sensitive applications. In addition to amplifiers deliver solid video performance into a 150 (ohm) load while consuming only 3.5mA per amplifier of supply current. This makes it ideal for applications where small size is essential. Each amplifier’s inputs and output are accessible providing added gain setting flexibility. These devices provide 30 mA of output current per amplifier, and are optimized for driving one back terminated video load (150 (ohm)) each. These current feedback amplifiers feature gain flatness of 0.1dB to 10MHz while offering differential gain and phase error of 0.05% and 0.1°. Both will operate from a single 5 to +12V power supply. The outputs of each amplifier swing to within 1.3V of either supply rail to accommodate video signals on a single +5V supply.
The high bandwidth of 100MHz, 500V/us of slew rate, along with settling to 0.1% in 25ns, make the AD8072 useful in many general purpose, high speed applications where a single +5V or dual power supplies up to +/-6V are needed. The AD8072 is available in 8-pin plastic DIP and SOIC packages.
