The LTC®6420-20 is a dual high-speed differenTIal amplifi er targeted at processing signals from DC to 300MHz. The part has been specifi 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 LTC6420-20 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 fi xed at 20dB (10V/V).The LTC6420-20 saves space and power compared to alternaTIve solutions using IF gain blocks and transform-ers. The LTC6420-20 is packaged in a compact 20-lead 3mm × 4mm QFN package and operates over the –40°C to 85°C temperature range.
