Overview
The AD539SD, produced by Analog Devices Inc., is a low distortion analog multiplier/divider integrated circuit. It features two identical signal channels (Y1 and Y2) with a common X input that provides linear control of gain. This device is designed for high-speed applications, offering excellent AC characteristics up to video frequencies and a -3 dB bandwidth of over 60 MHz. The AD539SD is fully calibrated and monolithic, with scaling accurately determined by a band-gap voltage reference and critical parameters laser-trimmed during manufacture.
