... ADCs with low noise and low distortion, but can also be used as a general-purpose broadband gain block. The LTC6400-26 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 of transformers or AC-coupling ca- pacitors in many applications. The gain is internally fi ...

... Moreover, they offer single-ended 50Ω matching in wideband applications and no external resistor is needed. The LTC6400-26 is very fl exible in terms of I/O coupling. It can be AC- or DC-coupled at the inputs, the outputs or both. Due to the internal connection between input and output, users are advised to keep input common mode voltage between 1V and 1 ...
