The CLC449 is an ultra-high-speed monolithic op amp, with a typical -3dB bandwidth of 1.1GHz at a gain of +2. This wideband op amp supports rise and fall times less than 1ns, settling time of 6ns (to 0.2%) and slew rate of 2500V/s. The CLC449 achieves 2nd harmonic distortion of -68dBc at 5MHz at a low supply current of only 12mA. These performance advantages have been achieved through improvements in National's proven current feedback topology combined with a high-speed complementary bipolar process.
