The RHF350 is a high-speed low-noise amplifier from STMicroelectronics with a bandwidth of 550 MHz, a static current of 4.1 mA, a slope of 940 V/µs, an input noise of 1.5 nV/√ Hz, a distortion of -66 dBc, a minimum output swing of 2.8 Vpp, and a 5 V power supply.
The RHF350 is a current feedback operational amplifier designed for very high speed applications with a bandwidth of up to 410 MHz and a slew rate of 940 V/us. It operates from a single 5 V power supply with a quiescent current of only 4.1 mA. The device is optimized for driving a standard 100 Ω load and is available in a Flat-8 hermetic ceramic package.
