AD534TH

Overview

The AD534TH is a space-qualified monolithic laser-trimmed four-quadrant analog multiplier and divider die manufactured by Analog Devices Inc. It operates within a supply voltage range of ±15 V and supports a temperature range from -55 °C to +125 °C. The device features a maximum multiplication error of ±0.25% for the AD534L variant without external trimming, with a pretrimmed scale factor of 10.00 V adjustable via an external resistor. It utilizes a 10-terminal uncased chip package designed for military and space applications under MIL-PRF-38534 Class K qualification.

Feature Summary

• Internally trimmed precision architecture ensuring high accuracy without external calibration
• Fully differential, high-impedance inputs on all terminals including the Z-input
• Space-qualified construction compliant with MIL-PRF-38534 Class K standards

Applications

• High-quality analog signal processing in aerospace environments
• 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 specific suffix TH corresponds to the intended space-qualified die configuration under MIL-PRF-38534 Class K. Confirm compatibility with the required 10-terminal uncased chip form factor and ±15 V supply requirements. Ensure the application environment falls within the specified -55 °C to +125 °C operating temperature range. Cross-reference the exact part number against official Analog Devices documentation to confirm current availability and qualification status.

Selection Notes

Select the AD534TH when space-qualified performance and high precision are required for analog computation tasks. This component is suitable for applications demanding fully differential operation and low noise characteristics. Consider the uncased die package constraints during PCB layout and assembly planning. Evaluate the need for external scaling resistors if the standard 10.00 V scale factor requires adjustment.

Part Context

The AD534 series represents a family of internally trimmed precision IC multipliers known for their monolithic construction and stability. The AD534TH specifically denotes the space-qualified die version, adhering to rigorous military reliability standards. It shares core functional characteristics with other AD534 variants but is distinguished by its radiation-hardened design and qualification for harsh environmental conditions.
