AD834AR

Overview

The AD834AR is a monolithic, laser-trimmed four-quadrant analog multiplier manufactured by Analog Devices Inc. It operates from DC to over 500 MHz with differential ±1 V full-scale inputs and differential ±4 mA full-scale output currents. The device functions on power supplies ranging from ±4 V to ±9 V, consuming approximately 280 mW at ±5 V. It features low distortion of ≤0.05% at 0 dBm input and a typical total full-scale error of 0.5%. Packaged in an 8-SOIC format, it is rated for the commercial temperature range of 0°C to 70°C.

Feature Summary

• High-frequency operation exceeding 500 MHz bandwidth suitable for demanding RF applications
• Laser-trimmed precision ensuring absolute calibration and minimal full-scale error
• Differential current output architecture compatible with external conversion circuits

Applications

• RF modulation and demodulation systems
• Variable gain amplifier control loops
• Frequency mixing and translation circuits

Procurement Notes

Verify the specific suffix AR indicates the 8-SOIC package variant when sourcing. Confirm the component status as obsolete or active through official Analog Devices channels prior to procurement. Ensure the supplier provides valid traceability documentation for this specific part number to guarantee authenticity and compliance with required specifications.

Selection Notes

Select the AD834AR when high-speed signal processing is required within the commercial temperature range. The differential current output necessitates external components such as transformers or operational amplifiers for voltage conversion. Consider the ±1 V input requirement and ensure supply voltages remain within the ±4 V to ±9 V limits for optimal performance and stability.

Part Context

The AD834 series comprises high-performance analog multipliers designed for broadband applications. The base AD834 model offers various packaging options including PDIP, CERDIP, and SOIC. The AD834AR specifically denotes the surface-mount SOIC variant intended for commercial use, maintaining the core high-bandwidth multiplication capabilities of the family while adapting to modern PCB assembly requirements.
