LMH6640
TFT-LCD Single, 16V Rail-to-Rail High Output
Operational Amplifier
General Description
The LMH6640 is a voltage feedback operational amplifier
with a rail-to-rail output drive capability of 100 mA. Employ-
ing National’s patented VIP10 process, the LMH6640 deliv-
ers 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 re-
sponse 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˚.
