Overview
The AD633JR, produced by Analog Devices Inc., is a functionally complete, four-quadrant analog multiplier. It is designed to offer high accuracy and stability in a cost-effective package. The device features high impedance differential X and Y inputs, as well as a high impedance unity-gain summing input (Z). The output voltage is a nominal 10 V full scale, provided by a buried Zener reference. The AD633JR is available in 8-lead SOIC and PDIP packages, making it easy to integrate into various analog circuits without the need for external components or user calibration.
