HFA1100IP

Instrumentation, Op Amps, Buffer Amps Overview

The HFA1100IP is a high-speed, wideband current feedback operational amplifier manufactured by Renesas Electronics Corporation. It is built using Intersil's proprietary complementary bipolar UHF-1 process technology. The device is designed for applications requiring fast settling times and low distortion. It operates with single supply voltages as low as 4.5V. Key electrical characteristics include an 850MHz -3dB bandwidth and a very fast slew rate of 2300V/μs. The amplifier provides excellent gain flatness and high output current capabilities.
