AD633ARZ-R7

Overview

The AD633ARZ-R7 is a 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 voltage output scaled to a nominal 10V full-scale range via an embedded Zener diode. Key electrical parameters include a small-signal bandwidth of 1MHz at VO=0.1V rms, a slew rate of 20V/μs at VO=20V p-p, and a typical supply current of 4mA. Total error remains within 2% of full scale. It operates on supply voltages ranging from ±8V to ±18V and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated laser-trimmed accuracy and stability for precise signal processing without external calibration components.
• High-impedance unit-gain summing input allows flexible configuration for adding outputs, adjusting gain, or converting voltage to current.
• Low noise performance with a spectral density of 0.8µV/√Hz for clean signal multiplication.

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 'R7' corresponds to the reel packaging format required for your assembly line. Confirm that the SOIC-8 package dimensions align with your PCB footprint design. Ensure the operating voltage range of ±8V to ±18V matches your power supply rails. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a complete analog multiplier solution is needed without external resistors or capacitors for basic scaling. The integrated 10V full-scale output simplifies interfacing with subsequent stages. Consider the 1MHz bandwidth limit for high-frequency applications. The SOIC-8 package offers a compact surface-mount option for space-constrained designs requiring industrial temperature stability.
