Description

The LMH6639 is a voltage feedback operational amplifier with a rail-to-rail output drive capability of 110mA. Employing TI’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/μs resulting in a full power bandwidth of approximately 28MHz. The LMH6639 also offers protection for the input transistors by using two anti-parallel diodes and a series resistor connected across the inputs. The TON value of 83nsec combined with a settling time of 33nsec makes this device ideally suited for multiplexing applications (see application note for details). 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°
