The LTC® 6400-20 is a high-speed differential ampli ertargeted at processing signals from DC to 300MHz. The part has been speci cally 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 LTC6400-20 is easy to use, with minimal support circuitry required. The output common mode voltage is set using an external pin, independent of the inputs, which eliminates the need for transformers or AC-coupling ca-pacitors in any applications. The gain is internally xed at 20dB (10V/V).
The LTC6400-20 saves space and power compared to alternative solutions using IF gain blocks and transform-ers. The LTC6400-20 is packaged in a compact 16-lead3mm* 3mm QFN package and operates over the -40 to 85mperature range
