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

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.
