The AD834 is a monolithic, laser-trimmed four-quadrant analog multiplier intended for use in high frequency applications, with features such as high precision, low distortion and low power consumption. It features a gain-symmetric dual op amp circuit with differential inputs and differential outputs, and is suitable for high frequency signal processing applications such as high speed real time computation, wideband modulation and gain control, signal correlation and RF power measurement, voltage controlled filters and oscillators, linear keyers for high resolution television and wideband true RMS.
