AD534KH

Overview

The AD534KH is a space-qualified, monolithic laser-trimmed four-quadrant analog multiplier and divider die manufactured by Analog Devices. It operates within a supply voltage range of ±15 V (nominal) and withstands temperatures from -55 °C to +125 °C. The component features a 10-terminal uncased chip package with no leads, designed for surface mount integration. It guarantees a maximum multiplication error of ±0.25% without external trimming and includes an internally trimmed scale factor of 10.00 V.

Feature Summary

• Monolithic laser-trimmed construction ensuring high accuracy previously limited to hybrid modules
• Fully differential, high-impedance inputs on all terminals including the Z-input
• Space-qualified die meeting MIL-PRF-38534 Class K requirements
• Low noise design with excellent long-term stability due to thin film resistors

Applications

• High-quality analog signal processing in aerospace systems
• 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 that the received component matches the AD534KH designation and confirms compliance with MIL-PRF-38534 Class K qualification standards. Ensure handling procedures account for the uncased die format and leadless terminal configuration. Confirm temperature rating specifications align with the required operational environment limits before integration into final assemblies.

Selection Notes

Select this component when space-qualified analog multiplication or division is required in harsh environments. It is suitable for applications demanding high accuracy without external trimming and fully differential input operation. Consider the uncased die form factor and specific packaging requirements for custom substrate mounting during system design.

Part Context

The AD534KH belongs to the AD534 family of precision analog multipliers. While standard versions are available in TO-100 packages, the KH suffix denotes a space-qualified die variant. This family utilizes buried Zener references and thin-film resistors to maintain performance under adverse conditions, offering flexibility through adjustable scale factors.

Replacement Considerations

Standard AD534L devices offer similar electrical characteristics but lack the specific space-qualification documentation. Verify if the uncased die form factor is compatible with existing board layouts when substituting packaged variants.
