Application Notes
(Continued)
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
COM
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 SOT23-5 pack-
age. All this performance is achieved at the low power con-
sumption of 65 mW which is of utmost importance in today’s
battery driven TFT panels.
