LTC6400IUD-20#PBF

LTC6400-20 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 16bit ADCs with low noise and low distortion, but can also be used as a general-purpose broadband gain block. It 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 at 20dB (10V/V). It is used in applications such as differential ADC driver, differential driver/receiver, single ended to differential conversion, IF sampling receivers, SAW filter interfacing.
