input and produces an output voltage referred to a user-chosen  
level. T he undesired common-mode signal is rejected, even at  
high frequencies. High impedance inputs ease interfacing to fi-  
nite source impedances and thus preserve the excellent  
common-mode rejection. In many respects, it offers significant  
improvements over discrete difference amplifier approaches, in  
particular in high frequency common-mode rejection.

T he wide common-mode and differential-voltage range of the  
AD830 make it particularly useful and flexible in level shifting  
applications, but at lower power dissipation than discrete solu-  
tions. Low distortion is preserved over the many possible differ-  
ential and common-mode voltages at the input and output.

Good gain flatness and excellent differential gain of 0.06% and  
phase of 0.08° make the AD830 suitable for many video system  
applications. Furthermore, the AD830 is suited for general pur-  
pose signal processing from dc to 10 MHz.  
T he AD830 is a wideband, differencing amplifier designed for  
use at video frequencies but also useful in many other applica-  
tions. It accurately amplifies a fully differential signal at the
