The LMH6550 device is a high-performance voltage feedback differential amplifier. The LMH6550 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 LMH6550 can handle a wide range of video and data formats.

With external gain set resistors, the LMH6550 can be used at any desired gain. Gain flexibility coupled with high speed makes the LMH6550 suitable for use as an IF amplifier in high-performance communications equipment.

The LMH6550 is available in the space-saving SOIC and VSSOP packages.
