Rad-Hard 1GHz low noise CMOS Single Opamp
  • active Active

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 Ω 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-8S hermetic ceramic package, which saves board space and provides excellent thermal and dynamic performance.
