190MHz Rail-to-Rail Output Amplifier With Disable

The LMH6639 is a voltage feedback Operational Amplifier with a Rail-to-Rail output drive capability of 110mA. Employing National's patented VIP10 process, the LMH6639 delivers a bandwidth of 190MHz at a current consumption of only 3.6mA. An input common mode voltage range extending to 0.2V below the V- and to within 1V of V+, makes the LMH6639 a true single supply op-amp. The output voltage range extends to within 30mV of either supply rail providing the user with a dynamic range that is especially desirable in low voltage applications.
The LMH6639 offers a slew rate of 172V/?s resulting in a full power bandwidth of approximately 28MHz. The TON value of 83nsec combined with a settling time of 33nsec makes this device ideally suited for multiplexing applications. Careful attention has been paid to ensure device stability under all operating voltages and modes. The result is a very well behaved frequency response characteristic for any gain setting including +1, and excellent specifications for driving Video cables including harmonic distortion of -60dBc, differential gain of 0.12% and differential phase of 0.045
