3 Description
The LMH6551 device is a high-performance voltage
feedback differential amplifier and is part of the
LMH™ integrated circuits family of devices. 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 formats.
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 VSSOP packages.
