AD830AR [Analog Devices]

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 preserve excellent common-mode rejection. It offers significant improvements over discrete difference amplifier approaches, particularly in high-frequency common-mode rejection. The wide common-mode and differential voltage range makes it flexible in level-shifting applications at lower power dissipation than discrete solutions. Low distortion is preserved over many possible differential and common-mode voltages at the input and output.
