LINEAR TECHNOLOGY  LTC6417CUDC#PBF  差分放大器, 高线性度, 1 放大器, -0.1 mV, 0 dB, 1.6 GHz, 0 °C, 70 °C

The is a differential Unity Gain Buffer that can drive a 50R load with extremely low noise and excellent linearity. It is well suited for driving high speed 14- and 16-bit pipeline ADCs with input signals from DC to beyond 600MHz. Differential input impedance is 18.5kR, allowing 1:4 and 1:8 transformers to be used at the input providing additional system gain in 50R systems. With no external biasing or gain setting components and a flow-through pinout, the LTC6417 is very easy to use. It can be DC-coupled and has a common mode output offset of -60mV. The LTC6417 input pins are internally biased to provide an output common mode voltage that is set by the voltage on the VCM pin for AC-coupled applications. Supply current is typically 123mA and the LTC6417 operates on supply voltages ranging from 4.75 to 5.25V. Power consumption can be reduced to 74mA via the PWRADJ pin. The LTC6417 also has a hardware shutdown feature which reduces current consumption to 24mA.
