AD834JR-REEL

Overview

The AD834JR-REEL is a monolithic, laser-trimmed four-quadrant analog multiplier manufactured by Analog Devices Inc. It operates with a transconductance bandwidth exceeding 500 MHz from differential voltage inputs when loaded with 50 Ω. The device features differential ±1 V full-scale inputs and provides a differential ±4 mA full-scale output current. It functions within supply voltages ranging from ±4 V to ±9 V, typically consuming 280 mW at ±5 V supplies. The component is housed in an 8-pin SOIC package.

Feature Summary

• Monolithic construction utilizing high-speed bipolar process technology for stable biasing based on band gap reference generators.
• Differential open collector outputs designed for external current-to-voltage conversion via transformers, baluns, or active circuits.
• Low distortion performance suitable for precision signal processing applications.

Applications

• High speed real time computation
• Wideband modulation and gain control
• Signal correlation and RF power measurement

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and reel configuration. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the ordering part number matches the required temperature grade and packaging format specified in the manufacturer datasheet before procurement.

Selection Notes

Select this component for applications requiring wideband analog multiplication without digital conversion latency. Consider the need for external load resistors or transformers to convert the differential current output to a single-ended voltage. Evaluate thermal dissipation requirements relative to the chosen supply voltage and ambient operating conditions.

Part Context

This part belongs to the AD834 family of high-frequency analog multipliers. It shares core architectural features with other variants in the series but differs in packaging and tape-and-reel specifications. The JR-REEL designation indicates a specific surface-mount package variant supplied in reels for automated assembly processes.

Replacement Considerations

Direct pin-compatible replacements are not explicitly confirmed in public data. Verify functional equivalence regarding bandwidth, input/output scaling, and supply voltage ranges if substituting with other four-quadrant multipliers.
