LMH6551Q
Differential, High Speed Op Amp
General Description
Features
The LMH®6551 is a high performance voltage feedback differential amplifier. The LMH6551Q 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
LMH6551Q can handle a wide range of video and data formats.
With external gain set resistors, the LMH6551Q can be used
at any desired gain. Gain flexibility coupled with high speed
makes the LMH6551Q suitable for use as an IF amplifier in
high performance communications equipment.
The LMH6551Q is available in the MSOP package.
