Data Sheet
October 26, 2004
FN2945.9
850MHz, Low Distortion Current Feedback
Operational Amplifiers
The HFA1100 is a high-speed, wideband, fast settling
current feedback amplifier built with Intersil's proprietary
complementary bipolar UHF-1 process. It operates with
single supply voltages as low as 4.5V (see Application
Information section).
The HFA1100 is a basic op amp with uncommitted pins 1, 5,
and 8.
This device offers a significant performance improvement
over the AD811, AD9617/18, the CLC400-409, and the
EL2070, EL2073, EL2030.
