DESCRIPTIO  
FEATURES  
■
800MHz –3dB Bandwidth  
The LT®1993-2 is a low distortion, low noise Differential  
Amplifier/ADC driver for use in applications from DC to  
800MHz. The LT1993-2 has been designed for ease of  
use, with minimal support circuitry required. Exception-  
ally low input-referred noise and low distortion products  
(with either single-ended or differential inputs) make the  
LT1993-2 an excellent solution for driving high speed 12-  
bit and 14-bit ADCs. In addition to the normal unfiltered  
outputs (+OUT and –OUT), the LT1993-2 has a built-in  
175MHz differential low pass filter and an additional pair  
of filtered outputs (+OUTFILTERED, –OUTFILTERED) to  
reduce external filtering components when driving high  
speedADCs.Theoutputcommonmodevoltageiseasilyset

Differential ADC Driver for:  
The LT1993-2 is designed to meet the demanding require-  
ments of communications transceiver applications. It can  
be used as a differential ADC driver, a general-purpose  
differential gain block, or in any other application requir-  
ing differential drive. The LT1993-2 can be used in data  
acquisition systems required to function at frequencies  
down to DC.
