Linear Technology announces the LTC6417, a fully differential buffer amplifier with only 1.5nV/√Hz output-referred noise. The LTC6417 is capable of driving a differential 50 Ohm load and is optimized for driving 14- and 16-bit pipeline ADCs. It can be DC- or AC-coupled at its inputs, and achieves excellent distortion performance for signals up to and beyond 600 MHz. At 140 MHz, OIP3 is 46 dBm, and HD3 is -69 dBc with 2.4 VP-P output swing into a 50Ohm load.
