AD834JN

Overview

The AD834JN 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 ±1 V full-scale inputs and differential ±4 mA full-scale output currents.

Feature Summary

• Monolithic four-quadrant multiplication capability
• High-speed operation with bandwidth exceeding 500 MHz
• Laser-trimmed accuracy with low total full-scale error
• Differential current outputs requiring external conversion

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 'JN' against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required supply voltages and input/output configurations. Check for availability of compatible replacement packages if the specific variant is discontinued or limited.

Selection Notes

Select this component when high-frequency analog multiplication is required. Consider the need for external circuitry to convert differential current outputs to single-ended voltage signals. Evaluate thermal management requirements based on typical power dissipation at the intended supply voltage.

Part Context

The AD834 series includes variants such as AD834ARZ and AD834JRZ. These parts share core functionality but differ in packaging and temperature ranges. The AD834JN belongs to this family of wideband multipliers manufactured by Analog Devices Inc.

Replacement Considerations

Official substitutes include AD834ARZ and AD834JRZ. Verify pinout and electrical specifications match before substitution.
