LTC6400-14 - Linear Technology

LTC6400-14 Low Distortion Differential ADC Driver

The LTC®6400-14 is a high-speed differential amplifier targeted at processing signals from DC to 300MHz. The part has been specifically designed to drive 12-, 14- and 16-bit ADCs with low noise and low distortion, but can also be used as a general-purpose broadband gain block. The LTC6400-14 is easy to use, with minimal support circuitry required. The output c.
