Description
The RHF350 is a current feedback operational
amplifier that uses very high speed
complementary technology to provide a
bandwidth of up to 410 MHz while drawing only
4.1 mA of quiescent current. With a slew rate of
940 V/s 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.
