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 commonmode rejection. In many respects, it offers significant improvements over discrete difference amplifier approaches, in particular in high frequency common-mode rejection.
