n 3mm × 4mm 20-Lead QFN Package The LTC®6417 is a differential unity gain buffer that can
drive a 50Ω load with extremely low noise and excellent
linearity. It is well suited for driving high speed 14-and
16-bit pipeline ADCs with input signals from DC to beyond
600MHz. Differential input impedance is 18.5kΩ, allowing …
