The LMH6640 is a voltage feedback operational amplifier with a rail-to-rail output drive capability of 100 mA. Employing TI’s patented VIP10 process, the LMH6640 delivers a bandwidth of 190 MHz at a current consumption of only 4mA. An input common 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 mV 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 dB). 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 dBc @ 5 MHz, differential gain of 0.12% and differential phase of 0.12°.
