AD534KDZ

Overview

The AD534KDZ is a precision analog multiplier and divider manufactured by Analog Devices Inc. It features a four-quadrant architecture capable of performing multiplication, division, squaring, and square root operations with high accuracy. The device is housed in a 14-lead ceramic dual in-line package (CDIP) designed for through-hole mounting. It operates within an industrial temperature range of 0°C to +70°C and supports a maximum operating frequency of 1 MHz. The component requires dual power supplies, typically ±15V, with a minimum supply voltage range of ±10V.

Feature Summary

• Four-quadrant analog multiplication and division capability
• Precision internal trimming for high accuracy performance
• Robust ceramic dual in-line packaging for reliable operation

Applications

• Signal processing systems requiring analog computation
• Frequency modulation and demodulation circuits
• Automatic gain control loops

Procurement Notes

Verify the specific suffix KDZ against official Analog Devices documentation to confirm the commercial grade temperature rating and ceramic package variant. Cross-reference the manufacturer part number with current datasheets to ensure compatibility with existing system designs, as availability status may vary. Confirm that the 14-CDIP footprint matches the target PCB layout requirements before procurement.

Selection Notes

Select this component when a monolithic solution for precise analog mathematical operations is required. The four-quadrant functionality allows handling both positive and negative input signals. Ensure the application environment stays within the specified 0°C to +70°C range. Verify that the system can accommodate the necessary dual power supply rails and that the 1 MHz bandwidth meets the signal processing speed requirements.

Part Context

This component belongs to the AD534 family of precision analog multipliers. It serves as a fundamental building block for linear signal processing applications where high fidelity multiplication or division is critical. The device integrates multiple transistor stages into a single compact unit, reducing the need for discrete component assembly and improving overall circuit reliability compared to hybrid solutions.
