LTC6400-8
2.2GHz Low Noise, Low
Distortion Differential ADC
Driver for DC-300MHz
FEATURES DESCRIPTION n The LTC®6400-8 is a 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. n 2.2GHz –3dB Bandwidth

Small 16-Lead 3mm × 3mm × 0.75mm QFN Package APPLICATIONS n The LTC6400-8 is easy to use, with minimal support circuitry required. The output common mode voltage is set
using an external pin, independent of the inputs, which
eliminates the need for transformers or AC-coupling capacitors in many applications. The gain is internally fixed …
