AD633JR-REEL7

Overview

The AD633JR-REEL7 is a functionally complete four-quadrant analog multiplier manufactured by Analog Devices Inc. It features high impedance differential X and Y inputs, along with a high impedance summing input (Z). The device provides a low impedance output voltage with a nominal 10 V full-scale range, derived from an internal buried Zener reference. Laser-trimmed for accuracy, it ensures total error remains within 2% of full scale. Operating on dual supplies ranging from ±8 V to ±18 V, it draws a typical supply current of 4 mA. The component is housed in an 8-lead SOIC package and supports operation temperatures up to +85 °C.

Feature Summary

• Laser-trimmed accuracy ensuring total error stays within 2% of full scale
• High impedance differential X and Y inputs for signal interfacing
• Integrated buried Zener providing a nominal 10 V full-scale output reference
• Complete four-quadrant multiplication without requiring external components

Applications

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

Procurement Notes

Verify the specific suffix REEL7 confirms tape-and-reel packaging when sourcing. Confirm the manufacturer designation matches Analog Devices Inc. to ensure authenticity. Check RoHS compliance status against current regulatory requirements. Validate that the SOIC-8 package dimensions align with your PCB footprint constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring precise analog multiplication without external calibration. Ensure the power supply rails fall within the ±8 V to ±18 V operational range. Verify that the load capacitance does not exceed the drive capability specified in the datasheet. Consider the thermal dissipation limits of the SOIC-8 package under maximum operating conditions.

Part Context

This part belongs to the AD633 family of low-cost analog multipliers. It shares functional similarities with the AD633JNZ and AD633JRZ but differs in packaging format. The REEL7 suffix indicates reel packaging suitable for automated assembly processes, distinguishing it from tube-packaged variants like the JRZ.

Replacement Considerations

Direct substitutes include AD633JRZ and AD633JNZ. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet the same laser-trimmed accuracy and electrical specifications.
