AD534LHZ

Overview

The AD534LHZ is a monolithic, laser-trimmed four-quadrant analog multiplier and divider manufactured by Analog Devices Inc. It operates within 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 terminals. The internal scale factor is pretrimmed to 10.00 V but can be adjusted via an external resistor to values as low as 3 V.

Feature Summary

• Internally trimmed precision architecture ensuring high accuracy without user calibration
• Fully differential, high-impedance input configuration on all signal terminals
• Adjustable scale factor allowing gain modification through external resistance
• Low noise design optimized for high-quality analog signal processing

Applications

• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis
• Wideband, high-crest rms-to-dc conversion
• Accurate voltage controlled oscillators and filters

Procurement Notes

Verify the specific suffix 'L' against official documentation to confirm the guaranteed ±0.25% multiplication error specification. Confirm the TO-100-10 metal can package type matches system requirements. Check current availability status as distribution may vary. Ensure environmental compliance data aligns with project constraints before finalizing procurement.

Selection Notes

Select this component when high-precision analog multiplication or division is required without external trimming overhead. The fully differential input structure provides flexibility in circuit design compared to single-ended alternatives. Consider the adjustable scale factor feature if variable gain control is necessary. Evaluate the low noise characteristics against system signal integrity requirements.

Part Context

The AD534 series represents a family of internally trimmed precision IC multipliers. The AD534LHZ variant specifically denotes the version with enhanced error specifications. It shares core architectural features with other AD534 models but differs in performance tolerances and packaging options available from Analog Devices Inc.
