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 to slew rate limiting.
The AD9617J operates over the range of 0°C to +70°C and is
available in either an 8-lead plastic DIP or an 8-1ead plastic
small outline package (SOIC).
