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 external compensation.
The AD9617 offers outstanding performance in high fidelity, wide bandwidth applications in instrumentation ranging from network and spectrum analyzers to oscilloscopes, and in military systems such as radar, SIGINT and ESM systems.
The superior slew rate, low overshoot and fast settling of the AD9617 allow the device to be used in pulse applications such as communications receivers and high speed ATE.
Most monolithic op amps suffer in these precision pulse applications due ...
