AD633ARZ-RL

Overview

The AD633ARZ-RL is a four-quadrant analog multiplier manufactured by Analog Devices Inc. in an 8-lead SOIC package. It operates on supply voltages ranging from 8 V to 18 V with a typical supply current of 4 mA. The device features a small-signal bandwidth of 1 MHz and a slew rate of 20 V/µs. Total error is within 2% of full scale, and the output noise spectral density is typically 0.8 nV/√Hz. It functions across a temperature range of -40°C to +85°C.

Feature Summary

• Four-quadrant multiplication capability allowing positive or negative input signals
• Laser-trimmed accuracy and stability with total error within 2% of full scale
• Integrated 10 V scaling reference eliminating external components for basic operation
• High impedance differential X and Y inputs with a high impedance unity-gain summing Z input

Applications

• Modulation and demodulation circuits including AM generation and synchronous detection
• Voltage-controlled amplifiers and attenuators
• Frequency conversion and mixing applications
• Analog computation tasks such as squaring and division

Procurement Notes

Verify the specific suffix RL indicates tape and reel packaging when ordering. Confirm the operating voltage range matches the system requirements between 8 V and 18 V. Ensure the thermal management supports the specified junction temperature limits. Check for RoHS compliance status if required by assembly standards. Validate pinout compatibility with existing PCB footprints for the SOIC-8 package.

Selection Notes

Select this component for designs requiring precise analog multiplication without external calibration. The integrated scaling reference simplifies circuit design compared to discrete solutions. Consider the 1 MHz bandwidth limit for high-frequency signal processing needs. Evaluate the power dissipation capabilities relative to the ambient temperature conditions. Verify that the input common-mode ranges align with the available signal levels.

Part Context

This part belongs to the AD633 family of analog multipliers produced by Analog Devices. It shares functional characteristics with other variants like the AD633ANZ but differs in packaging and reel configuration. The series is established for general-purpose analog computing and signal processing tasks requiring reliable four-quadrant performance.

Replacement Considerations

Cross-reference with AD633ARZ for identical functionality in tube packaging. Verify pin compatibility with legacy designs using the AD534 or AD632 families. Confirm electrical specifications match before substituting with generic multiplier ICs.
