AD633JRZ

Overview

The AD633JRZ is a complete four-quadrant analog multiplier housed in an 8-pin SOIC surface-mount package. It features high-impedance differential X and Y inputs alongside a high-impedance summing input (Z). The device provides a low-impedance output with a nominal 10V full-scale range derived from an internal buried Zener reference. Laser-trimmed for stability, it guarantees a total accuracy within 2% of full scale. Electrical specifications include a small-signal bandwidth of 1MHz, a slew rate of 20V/µs, and operation on dual power supplies ranging from ±8V to ±18V.

Feature Summary

• Complete four-quadrant multiplication capability without requiring external components
• Laser-trimmed precision ensuring total error remains within 2% of full scale
• High-impedance differential X and Y inputs minimize signal source loading
• Internal scaled reference voltage eliminates the need for expensive user calibration

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 'JRZ' corresponds to the 8-pin SOIC surface-mount package variant. Confirm the operating temperature range matches the industrial specification (-40°C to +85°C) rather than the commercial grade. Ensure the datasheet confirms the laser-trimmed accuracy claims before finalizing component selection for precision applications.

Selection Notes

Select this component when a cost-effective, single-chip solution for analog signal processing is required. It is suitable for designs needing high input impedance and minimal external circuitry. Consider the 1MHz bandwidth limit for high-frequency applications. Verify that the ±8V to ±18V supply range aligns with the system power architecture.

Part Context

This part belongs to the AD633 family of analog multipliers manufactured by Analog Devices Inc. The series is designed to provide accurate signal processing functions in a compact form factor. The JRZ designation specifically identifies the surface-mount plastic package version, distinguishing it from through-hole or other package variants within the same functional family.

Replacement Considerations

Check for direct pin-compatible alternatives such as the AD633JNZ (PDIP) or AD633ARZ (SOIC) if package changes are permissible. Verify that any substitute maintains the same four-quadrant functionality and laser-trimmed accuracy specifications.
