AD534TH/883B

Overview

The AD534TH/883B is a monolithic, laser-trimmed four-quadrant analog multiplier and divider manufactured by Analog Devices Inc. under the MIL-PRF-38534 Class K space qualification standard. It features fully differential, high-impedance inputs for X, Y, and Z terminals, ensuring flexibility in signal processing applications. The device guarantees a maximum multiplication error of ±0.25% without external trimming and includes an on-chip thin-film resistor network with a buried Zener reference for long-term stability. It operates within a temperature range of -55°C to +125°C and utilizes a ceramic flat package.

Feature Summary

• Monolithic construction with internal laser trimming for precision performance
• Fully differential, high-impedance inputs on all channels including the Z-input
• Space-qualified reliability compliant with MIL-PRF-38534 Class K standards
• Integrated thin-film resistors and buried Zener reference for stability

Applications

• High-quality analog signal processing systems
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis
• Wideband, high-crest factor RMS-to-DC conversion
• Accurate voltage-controlled oscillators and filters

Procurement Notes

Verify that the specific suffix /883B confirms compliance with MIL-PRF-38534 Class K requirements for space applications. Confirm the package type matches the required thermal and mechanical constraints for the target environment. Ensure the ordering documentation explicitly references the military grade specification rather than commercial variants. Cross-reference the manufacturer's latest datasheet for any process change notices affecting this part number.

Selection Notes

Select this component when high accuracy and long-term stability are critical for aerospace or defense electronics. The fully differential input architecture simplifies circuit design by eliminating common-mode noise issues. Consider the pretrimmed scale factor and low noise characteristics for precision measurement tasks. Evaluate the thermal management requirements associated with the ceramic package in high-temperature environments.

Part Context

This part belongs to the AD534 family of precision analog multipliers. The /883B suffix denotes a specific military/space-grade version qualified under MIL-PRF-38534. It shares core functional specifications with commercial counterparts like the AD534L but offers enhanced reliability and environmental tolerance suitable for harsh operating conditions.
