FEATURES  
DESCRIPTION  
TheLTC®6420-20isadualhigh-speeddifferentialamplifier  
targeted at processing signals from DC to 300MHz. The  
part has been specifically designed to drive 12-, 14- and  
16-bitADCswithlownoiseandlowdistortion,butcanalso  
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,  
whicheliminatestheneedfortransformersorAC-coupling  
capacitors in many applications. The gain is internally  
fixed at 20dB (10V/V).
