AD534SH

Overview

The AD534SH 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 terminals, enabling flexible signal processing configurations. The device includes an on-chip thin-film resistor network and buried Zener reference to ensure excellent long-term stability and low temperature coefficients. Designed for precision applications, it offers guaranteed multiplication error specifications without external trimming and supports adjustable scale factors via external resistors.

Feature Summary

• Monolithic construction with internal laser trimming for high accuracy
• Fully differential, high-impedance inputs on all channels
• Integrated thin-film resistors and buried Zener reference for stability

Applications

• High-quality analog signal processing
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis

Procurement Notes

Verify the specific suffix 'SH' against official Analog Devices documentation to confirm package type, temperature range, and qualification status. Ensure compatibility with system requirements for differential input interfaces and supply voltages. Cross-reference with MIL-PRF-38534 standards if space-qualified variants are required for the application environment.

Selection Notes

Select this component when precise four-quadrant multiplication or division is required in a compact monolithic form factor. The differential input architecture simplifies circuit design for noise-sensitive applications. Consider the adjustable scale factor feature if gain flexibility is needed without additional amplification stages.

Part Context

The AD534 series represents a line of precision analog multipliers known for their internal trimming and stability. The AD534SH variant falls within this family, offering specialized packaging or qualification options suitable for demanding industrial or aerospace environments where long-term reliability and accuracy are critical.

Replacement Considerations

Check for direct equivalents such as the AD734 or AD834 series from Analog Devices. Verify pinout compatibility and electrical parameter alignment before substitution.
