LMH6551
Differential, High Speed Op Amp
General Description
The LMH™6551 is a high performance voltage feedback
differential amplifier. The LMH6551 has the high speed and
low distortion necessary for driving high performance ADCs
as well as the current handling capability to drive signals
over balanced transmission lines like CAT 5 data cables. The
LMH6551 can handle a wide range of video and data for-
mats.
With external gain set resistors, the LMH6551 can be used
at any desired gain. Gain flexibility coupled with high speed
makes the LMH6551 suitable for use as an IF amplifier in
high performance communications equipment.
The LMH6551 is available in the space saving SOIC and
MSOP packages.
