RHF350

Rad-hard 550MHz low noise Opamp
  • active Active

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-8 hermetic ceramic package, saving board space as well as providing excellent thermal and dynamic performance.
