Overview
The AD834JR-REEL is a monolithic, laser-trimmed four-quadrant analog multiplier produced by Analog Devices Inc. This component is designed for high-frequency applications, offering a transconductance bandwidth in excess of 500 MHz from either of the differential voltage inputs. It combines high static accuracy with very high bandwidth, making it suitable for a variety of nonlinear operations such as square rooting, analog division, vector addition, and rms-to-dc conversion.
