AD633JRZ-R7

Overview

The AD633JRZ-R7 is a four-quadrant analog multiplier integrated circuit 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 voltage output with a nominal 10V full-scale range, derived from an embedded Zener reference. Laser-trimmed for accuracy, it guarantees a total error of 2% of full scale. Key electrical specifications include a small-signal bandwidth of 1MHz, a slew rate of 20V/µs, and operation on dual supplies ranging from ±8V to ±18V. It is housed in an 8-pin SOIC package.

Feature Summary

• Four-quadrant analog multiplication capability
• Laser-trimmed precision ensuring total error within 2% of full scale
• High-impedance differential X and Y inputs
• Integrated Zener reference providing nominal 10V full-scale output

Applications

• Industrial signal processing
• Sensor interface circuits
• Test and measurement instrumentation
• Modulation and demodulation systems

Procurement Notes

Verify the specific suffix 'R7' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the operating temperature range and supply voltage requirements align with the system design constraints before finalizing procurement orders.

Selection Notes

Select this component when a complete, laser-calibrated analog multiplier solution is needed without external trimming components. It is suitable for applications requiring moderate bandwidth and high accuracy. Ensure the power supply rails fall within the specified ±8V to ±18V range to maintain performance specifications.

Part Context

This part belongs to the AD633 family of analog multipliers. It shares functional characteristics with other variants such as the AD633ARZ and AD633JNZ, differing primarily in packaging type and temperature rating. The JRZ variant specifically denotes the surface-mount SOIC package configuration.

Replacement Considerations

Compatible substitutes include AD633ARZ and AD633JNZ. Verify pinout compatibility and ensure the alternative package matches the PCB footprint requirements.
