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).
