As can be seen, the LMH6640 is capable of supplying up to 160 mA of output current and can settle the output
in 4.4 μs.
The LMH6640 is a cost effective amplifier for use in the TFT V

application and is made even more attractive
by its large supply voltage range and high output current. The combination of all these features is not readily
available in the market, especially in the space saving SOT-23 5 pin package. All this performance is achieved at
the low power consumption of 65 mW which is of utmost importance in today’s battery driven TFT panels.
