Description
The HFA1100, HFA1120 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.
