AD534TD

Overview

The AD534TD is a monolithic, laser-trimmed four-quadrant analog multiplier and divider manufactured by Analog Devices Inc. It features fully differential, high-impedance inputs for X, Y, and Z channels, ensuring flexibility in signal processing applications. The device includes an on-chip thin-film resistor network and buried Zener reference for long-term stability and low temperature coefficients. A pretrimmed scale factor of 10.00 V allows for adjustable gain via external resistors. Designed for precision operations, it guarantees a maximum multiplication error of ±0.25% without external trimming.

Feature Summary

• Monolithic construction with internal laser trimming for high accuracy
• Fully differential, high-impedance inputs on all channels including the Z-input
• Integrated thin-film resistors and buried Zener reference for stability
• Adjustable scale factor to provide up to X100 gain

Applications

• High-quality analog signal processing
• 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 TD against the manufacturer's current datasheet to confirm package type and temperature range specifications. Ensure compatibility with required supply voltages and input configurations for your circuit design. Cross-reference part numbers with official Analog Devices documentation to avoid counterfeit components and confirm availability status.

Selection Notes

Select this component when precise four-quadrant multiplication or division is required without external calibration. Its differential input architecture simplifies interface design for balanced signals. Consider the adjustable scale factor feature if gain flexibility is needed. Evaluate thermal performance and stability requirements against the integrated reference characteristics for adverse operating conditions.
