The LMH6551Q 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 VSSOP package.
