Description
The RHF330 is a current feedback operational
amplifier that uses very high-speed
complementary technology to provide a large
bandwidth of 1 GHz in gains of 2 while drawing
only 16.6 mA of quiescent current. The RHF330
also offers 0.1 dB gain flatness up to 160 MHz
with a gain of 2. With a slew rate of 1800 V/µs and
an output stage optimized for standard 100
loads, this device is highly suitable for
applications where speed and low distortion 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.
