LMH6551
- 370 MHz –3-dB Bandwidth
(VOUT = 0.5 VPP) - 50 MHz 0.1-dB Bandwidth
- 2400 V/µs Slew Rate
- 18 ns Settling Time to 0.05%
- –94/–96 dB HD2/HD3 at 5 MHz
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.
