Overview
The AD834ARZ-R7, produced by Analog Devices Inc., is a monolithic, laser-trimmed four-quadrant analog multiplier. It is designed for high-frequency applications, offering a transconductance bandwidth in excess of 500 MHz from either of the differential voltage inputs. This component is particularly useful in applications requiring high-speed nonlinear operations such as multiplication, squaring, and other complex signal processing tasks. The AD834ARZ-R7 is available in an 8-lead SOIC package and operates over the commercial temperature range of 0°C to 70°C.
