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.
