AD834JNZ

Overview

The AD834JNZ is a monolithic, laser-trimmed four-quadrant analog multiplier from Analog Devices. It features a transconductance bandwidth exceeding 500 MHz with differential ±1 V full-scale inputs and differential ±4 mA full-scale output currents. The device operates on supply voltages ranging from ±4 V to ±9 V, consuming typical power of 280 mW at ±5 V. It provides low distortion performance and maintains accuracy across temperature variations due to band gap reference biasing.

Feature Summary

• Monolithic four-quadrant analog multiplication capability
• High-speed operation with bandwidth exceeding 500 MHz
• Differential voltage inputs and current outputs
• Temperature-insensitive performance via band gap reference

Applications

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

Procurement Notes

Verify the specific suffix JNZ against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required supply voltages and input/output configurations for the target application. Confirm availability status through authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when high-frequency analog multiplication is required with minimal distortion. Consider the differential output nature, which may necessitate external current-to-voltage conversion circuits such as transformers or op-amps for single-ended applications. Evaluate thermal management requirements based on the specified power dissipation.

Part Context

The AD834 series represents a family of high-performance analog multipliers designed for demanding RF and communication applications. The JNZ variant specifically denotes the industrial temperature range and SOIC-8 package configuration within the broader AD834 product line offered by Analog Devices.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic equivalents may not match the 500 MHz bandwidth or laser-trimmed accuracy specifications.
