RHF350：Rad-hard 550MHz low noise Opamp
The RHF350 device is a current feedback operational amplifier that uses very high-speed
complementary technology to provide a bandwidth of up to 550 MHz while drawing only 4 mA of
quiescent current. With a slew rate of 940 V/µs and an output stage optimized for driving a
standard 100 Ω load, this circuit is highly suitable for applications where speed and
power-saving are the main requirements. The device is a single operator available in a Flat-8S
hermetic ceramic package, saving board space as well as providing excellent thermal and
dynamic performance.
