LMH6640 Datasheet | National Semiconductor

Description The LMH™6640 is a voltage feedback operational amplifier with a rail-to-rail output drive capability of 100 m A. Employing National’s patented VIP10 process, the LMH6640 delivers a bandwidth of 190 MHz at a current consumption of only 4m A. An input mon mode voltage range extending to 0.3V below the V- and to within 0.9V of V+, makes the LMH6640 a true single supply op-amp. The output voltage range extends to within 100 m V of either supply rail providing the user with a dynamic range that is especially desirable in low voltage applications. The LMH6640 offers a slew rate of 170 V/µs resulting in a full power bandwidth of approximately 28 MHz with 5V single supply (2 VPP, - 1 d B). 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 total harmonic distortion of - 64 d Bc @ 5 MHz, differential gain of 0.12% and differential phase of 0.12˚.
