AD834ARZ-RL

Overview

The AD834ARZ-RL is a wideband analog multiplier manufactured by Analog Devices Inc. It operates within the AD834 series and utilizes an 8-pin SOIC package for surface-mount installation. The device functions as a four-quadrant multiplier with differential inputs and low-impedance outputs. Electrical specifications include a typical dual supply voltage of ±5 V, operating between minimum ±4 V and maximum ±9 V. The unit draws 35 mA of working power supply current. It supports input voltages up to 1 V and delivers an output current of 4 mA with a maximum power dissipation of 500 mW.

Feature Summary

• Provides high-speed analog multiplication capabilities suitable for broadband applications
• Features differential X and Y inputs alongside a Z summing input for flexible signal processing
• Delivers low-impedance differential outputs capable of driving heavy loads directly

Applications

• RF modulation and demodulation circuits
• Automatic gain control systems
• Frequency mixing and conversion stages

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability status and lead times prior to procurement planning.

Selection Notes

Select this component when designing circuits requiring precise four-quadrant analog multiplication at high frequencies. The 8-pin SOIC package facilitates compact board layouts for surface-mount technology. Consider the ±5 V typical supply requirement and 35 mA current consumption during power budgeting. Verify that the 500 MHz bandwidth aligns with the system's signal frequency constraints.

Part Context

This component belongs to the AD834 family of wideband multipliers produced by Analog Devices. The family includes variants such as the AD834JRZ and AD834ARZ, which share similar functional architectures but differ in temperature grades and packaging formats. The AD834 series is engineered for demanding RF and IF applications requiring linear multiplication performance.

Replacement Considerations

The AD834JRZ serves as a commercial grade alternative within the same package footprint. The AD834ARZ offers industrial temperature range options in tube packaging. Verify pin compatibility and electrical parameter overlaps before substituting these parts.
