DESCRIPTIO  
FEATURES  
300 MHz –3dB Bandwidth  
The LT®6402-20 is a low distortion, low noise differential  
amplifier/ADC driver for use in applications from DC to  
300MHz. The LT6402-20 has been designed for ease of  
use,withminimalsupportcircuitryrequired.Exceptionally  
low input-referred noise and low distortion (with either  
single-ended or differential inputs) make the LT6402-20  
an excellent solution for driving high speed 12-bit and  
14-bit ADCs. In addition to the normal unfiltered outputs  
(+OUT and –OUT), the LT6402-20 has a built-in 75MHz  
differential low pass filter and an additional pair of filtered  
outputs (+OUTFILTERED, –OUTFILTERED) to reduce  
external filtering components when driving high speed  
ADCs. The output common mode voltage is easily set via

APPLICATIO S  
TheLT6402-20isdesignedtomeetthedemandingrequire-  
ments of communications transceiver applications. It can  
be used as a differential ADC driver, a general-purpose  
differential gain block, or in other applications requiring  
differential drive. The LT6402-20 can be used in data  
acquisition systems required to function at frequencies  
down to DC.
