850MHz, Low Distortion Current Feedback
Operational Amplifiers
The HFA1100, 1120 are a family of high-speed, wideband,
fast settling current feedback amplifiers built with Intersil's
proprietary complementary bipolar UHF-1 process. Both
amplifiers operate 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. The HFA1120 includes inverting input bias current
adjust pins (pins 1 and 5) for adjusting the output offset
voltage.
These devices offer a significant performance improvement
over the AD811, AD9617/18, the CLC400-409, and the
EL2070, EL2073, EL2030.
For Military grade product refer to the HFA1100/883,
HFA1120/883 data sheet.
