Analog Devices AN-309 Build Fast VCAs VCFs with Analog Multipliers Application Note
This document describes signal processing tasks achievable with a high-speed, monolithic, dual-channel analog multiplier. It focuses on the AD539 device, which allows for the design of megahertz-range voltage-controlled amplifiers (VCAs) and filters that exceed current digital technology capabilities.
The text details the operating principles of the 2-quadrant AD539 multiplier, including its input characteristics, gain control mechanisms, and transfer functions. It provides circuit examples such as a dual-channel VCA configuration using external operational amplifiers to achieve high bandwidth and low distortion.
