HFA1100

® HFA1100 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.
