GENERAL DESCRIPTION The AD9617 is a current feedback amplifier which utilizes a proprietary architecture to produce superior distortion and dc precision. It achieves this along with fast settling, very fast slew rate, wide bandwidth (both small signal and large signal) and exceptional signal fidelity. The device achieves –67 dBc 2nd harmonic distortion at 20 MHz while maintaining 190 MHz small signal and 150 MHz large signal bandwidths. These attributes position the AD9617 as an ideal choice for driving flash ADCs and buffering the latest generation of DACs. Optimized for applications requiring gain between ± 1 to ± 15, the AD9617 is unity gain stable without ex...
