Overview
The AD830JRZ, produced by Analog Devices Inc., is a wideband, differencing amplifier designed primarily for use at video frequencies but also suitable for various other applications. It accurately amplifies fully differential signals and produces an output voltage referenced to a user-chosen level, while rejecting undesired common-mode signals even at high frequencies. This amplifier is notable for its high impedance inputs, excellent common-mode rejection, and low distortion, making it a versatile component for signal processing from DC to 10 MHz.
