The AD539KNZ is a dual-channel wideband Linear Multiplier/Divider for use with high speed analogue division. The low distortion analogue multiplier has two identical signal channels (Y1 & Y2) with a common X input providing linear control of gain. Excellent AC characteristics up to video frequencies and a -3dB bandwidth of over 60MHz are provided. Although intended primarily for applications where speed is important, the circuit exhibits good static accuracy in computational applications. Scaling is accurately determined by a band-gap voltage reference and all critical parameters are laser-trimmed during manufacture. The full bandwidth can be realized over most of the gain range using the AD539 with simple resistive loads of up to 100R. The two channels provide flexibility. In single-channel applications, they can be used in parallel to double the output current, in series to achieve a square-law gain function with a control range of over 100dB or differentially to reduce distortio
