LMH6639
190MHz Rail-to-Rail Output Amplifier with Disable
General Description
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/μs resulting in a full
power bandwidth of approximately 28MHz. The T
ON
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 set-
ting including +1, and excellent specifications for driving
video cables including harmonic distortion of 60dBc, differ-
ential gain of 0.12% and differential phase of 0.045
