LTC6401IUD-20#PBF

LTC®6401-20 is a high-speed differential amplifier targeted at processing signals from DC to 140MHz. 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. The LTC6401-20 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. It is suitable for differential ADC driver, differential driver/receiver, single ended to differential conversion, IF sampling receivers, SAW filter interfacing applications.
