Analog Devices AD834 Manuals

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.

The document describes the features and characteristics of the AD834 500 MHz four-quadrant multiplier from Analog Devices. It operates from DC to 500 MHz, has differential ±1 V full-scale inputs and differential ±4 mA full-scale output current. It features low distortion, low power consumption, and is suitable for applications such as high-speed real-time computation, wideband modulation and gain control, signal correlation and RF power measurement, voltage-controlled filters and oscillators.
