AD834AQ

Overview

The AD834AQ is a monolithic, laser-trimmed four-quadrant analog multiplier designed for high-frequency applications. It features a transconductance bandwidth exceeding 500 MHz from differential voltage inputs. The device operates with supply voltages ranging from ±4 V to ±9 V and consumes low power, typically 280 mW at ±5 V supplies. It provides differential ±4 mA full-scale output currents.

Feature Summary

• Monolithic construction with laser trimming for precision
• High-speed operation with bandwidth greater than 500 MHz
• Low distortion performance for accurate signal processing
• Insensitive to temperature and supply variations

Applications

• High speed real time computation
• Wideband modulation and gain control
• Signal correlation and RF power measurement
• Linear keyers for high resolution television

Procurement Notes

Verify the specific suffix 'AQ' against official Analog Devices documentation to confirm military-grade qualification or extended temperature range specifications. Ensure compatibility with existing board layouts regarding the 8-pin SOIC package and differential current outputs requiring external conversion components.

Selection Notes

Select this component when high-frequency multiplication is required with minimal distortion. Consider the need for external current-to-voltage conversion circuits such as wideband transformers or op-amps to utilize the differential output effectively in single-ended systems.

Part Context

This part belongs to the AD834 family of analog multipliers. It shares core architectural features with variants like the AD834AR and AD834JRZ but may differ in qualification standards or environmental ratings based on the suffix designation within the manufacturer's product line.

Replacement Considerations

Direct pin-compatible substitutes include other AD834 variants such as AD834AR or AD834JRZ, provided their electrical characteristics and qualification levels meet the system requirements.
