20-Lead 3mm × 4mm × 0.75mm QFN Package APPLICATIONS n The LTC®6420-20 is a dual high-speed differential amplifier
targeted at processing signals from DC to 300MHz. The
part has been specifically designed to drive 12-, 14-and
16-bit ADCs with low noise and low distortion, but can also
be used as a general-purpose broadband gain block. …
