GENERAL DESCRIPTION
The 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
REV. B

input and produces an output voltage referred to a user-chosen
level. The undesired common-mode signal is rejected, even at
high frequencies. High impedance inputs ease interfacing to
finite source impedances and thus preserve the excellent com-
mon-mode rejection. In many respects, it offers significant
improvements over discrete difference amplifier approaches, in
particular in high frequency common-mode rejection.
The 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
differential 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-
purpose signal processing from dc to 10 MHz.
