AD633JR-REEL

Overview

The AD633JR-REEL is a functionally complete four-quadrant analog multiplier manufactured by Analog Devices Inc. It features high impedance differential X and Y inputs alongside a high impedance summing input (Z). The device provides a low impedance output voltage with a nominal 10 V full-scale range, established by an internal buried Zener reference. Laser-trimmed accuracy ensures total error remains within 2% of full scale. Packaged in an 8-lead SOIC format for surface mount applications, it operates without requiring external components for basic functionality.

Feature Summary

• Four-quadrant multiplication capability
• Laser-trimmed accuracy and stability
• High impedance unity-gain summing input
• Complete design requiring no external components

Applications

• Multiplication, division, and squaring operations
• Modulation and demodulation circuits
• Phase detection systems
• Voltage-controlled amplifiers and attenuators

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with surface mount assembly processes. Confirm that the selected variant meets the required operating temperature range and electrical tolerances for the intended application environment before finalizing procurement.

Selection Notes

Select this component when a cost-effective, complete analog multiplier solution is required without external calibration components. The SOIC package suits automated surface mount production lines. Consider the laser-trimmed precision and inherent stability for applications demanding reliable signal processing performance in industrial or instrumentation contexts.

Part Context
