The LTC®6416 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 12kΩ, 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. 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. In addition the LTC6416 has high speed, fast recovery clamping circuitry to limit output signal swing. Supply current is nominally 42mA and the LTC6416 operates on supply voltages ranging from 2.7V to 3.9V. The LTC6416 is packaged in a 10-lead 3mm × 2mm DFN package. Pinout is optimized for placement directly adjacent to Linear’s high speed 12-, 14- and 16-bit ADCs.
