The HFA1150 is a high-performance, 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.
The HFA1150 is a high‑speed, wideband current‑feedback operational amplifier built on Intersil's proprietary complementary bipolar UHF‑1 process. It offers low distortion, high slew rate, and can operate from a single 5 V supply down to 4.5 V, making it suitable for communication, video switching, and pulse‑amplifier applications.
The datasheet lists absolute maximum ratings, detailed electrical specifications such as 3 dB bandwidth up to 700 MHz (SOIC) or 540 MHz (SOT‑23), slew rate of 2700 V/µs, output current of 60 mA, and gain flatness of +0.05 dB to 100 MHz. It also includes application notes, recommended feedback resistor values, layout guidelines, and evaluation board information.
