Description

The HFA1150 is a high-speed, wideband, fast settling op amp built with Intersil's proprietary complementary bipolar UHF-1 process. The current feedback architecture delivers superb bandwidth even at very high gains (>300MHz at AV = 10), and the low distortion and excellent video parameters make this amplifier ideal for communication and professional video applications.

Though specified for ±5V operation, the HFA1150 operates with single supply voltages as low as 4.5V, and requires only 3.4mA of Icc in 5V applications (see Application Information section, and Application Note AN9891). For a lower power amplifier in a SOT-23 package, please refer to the HFA1155 data sheet.
