AD534JD

Overview

The AD534JD is a monolithic, laser-trimmed four-quadrant analog multiplier and divider manufactured by Analog Devices Inc. It operates within a military temperature range of -55°C to +125°C and utilizes a TO-100-10 metal can package. The device guarantees a maximum multiplication error of ±0.25% without external trimming. It features fully differential, high-impedance inputs for X, Y, and Z channels. The scale factor is pretrimmed to a standard value of 10.00 V, which can be adjusted via an external resistor.

Feature Summary

• Monolithic construction with internal laser trimming for precision
• Fully differential, high-impedance operation on all inputs including the Z-input
• Adjustable scale factor allowing gain reduction from the standard 10.00 V setting
• Low noise design optimized for high-quality analog signal processing

Applications

• High quality analog signal processing
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis
• Accurate voltage controlled oscillators and filters

Procurement Notes

Verify component authenticity through authorized distribution channels due to military-grade specifications. Confirm package integrity as the TO-100-10 metal can requires careful handling. Check current availability status as legacy military parts may have limited supply chains. Ensure environmental compliance documentation matches project requirements. Validate that the specific suffix corresponds to the required temperature grade and performance tier.

Selection Notes

Select this component when high accuracy and low drift are critical in harsh environments. The differential input architecture simplifies circuit design by eliminating common-mode interference issues. Consider the adjustable scale factor for flexibility in gain settings. Evaluate the long-term stability provided by the on-chip thin film resistors and buried zener reference for applications requiring sustained precision over time.

Part Context

The AD534 series represents a line of internally trimmed precision IC multipliers designed for demanding applications. The JD variant specifically denotes the military temperature range and TO-100-10 hermetic packaging. This family offers performance previously available only in expensive hybrid or modular products, providing a cost-effective monolithic solution for complex analog computations.

Replacement Considerations

Public confirmed substitute part numbers include AD534JHZ and AD534KHZ. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement meets the same military temperature and reliability standards.
