LTC6417 Datasheet 1.6GHz Low Noise High Linearity Differential Buffer/16-Bit ADC Driver

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®6417 is a differential unity gain buffer that can drive a 50Ω 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 18.5kΩ, allowing 1:4 and 1:8 transformers to be used at the input providing additional system gain in 50Ω systems.
