LTC6421-20 Dual Matched 1.3GHz Differential Amplifiers/ADC Drivers DESCRIPTION
The LTC®6421-20 is a dual high speed differential amplifier targeted at processing signals from DC to 140MHz.

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 LTC6421-20 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 capacitors in many applications. The gain is internally fixed at 20dB (10V/V). The LTC6421-20 saves space and power compared to alternative solutions using IF gain blocks and transformers. The LTC6421-20 is packaged in a compact 20-lead 3mm Ч 4mm QFN package and operates over the ­40°C to 85°C temperature range.
