Differential Amplifier/ADC Driver  
FEATURES  
DESCRIPTION  
The LTC®6409 is a very high speed, low distortion, dif-  
ferential amplifier. Its input common mode range includes  
ground, so that a ground-referenced input signal can be  
DC-coupled, level-shifted, and converted to drive an ADC  
differentially.

The gain and feedback resistors are external, so that the  
exact gain and frequency response can be tailored to each  
application. For example, the amplifier could be externally  
compensated in a no-overshoot configuration, which is  
desired in certain time-domain applications.

The LTC6409 is stable in a differential gain of 1. This  
allows for a low output noise in applications where gain  
is not desired. It draws 52mA of supply current and has  
a hardware shutdown feature which reduces current con-  
sumption to 100µA.
