The LTC6416 is a differential unity gain buffer designed to drive 16-bit ADCs with extremely low output noise and excellent linearity beyond 300MHz. Differential input impedance is 12k, allowing 1:4 and 1:8 transformers to be used at the input to achieve additional system gain. With no external biasing or gain setting components and a flow-through pinout, the LTC6416 is very easy to use. It can be DC-coupled and has a common mode output offset of 40mV. If the input signals are AC-coupled, the LTC6416 input pins are internally biased to provide an output common mode voltage that is set by the voltage on the VCM pin.
