GENERAL DESCRIPTION
The AD830 is a wideband, differencing amplifier designed for use
at video frequencies but also useful in many other applications. It
accurately amplifies a fully differential signal at the 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 common-
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 solutions.
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.
