AD534SD/883B

Overview

The AD534SD/883B is a monolithic, laser-trimmed four-quadrant analog multiplier and divider manufactured by Analog Devices. It operates within a military temperature range of -55°C to +125°C and utilizes a CDIP-10 package. The device guarantees a maximum multiplication error of ±0.25% without external trimming. It features fully differential, high-impedance inputs for X, Y, and Z channels. The internal scale factor is pretrimmed to 10.00 V but can be adjusted via an external resistor to values as low as 3 V.

Feature Summary

• Monolithic construction with laser-trimmed precision for guaranteed accuracy
• Fully differential, high-impedance operation on all input channels including the Z-input
• Integrated thin-film resistors and buried Zener reference for long-term stability
• Adjustable scale factor allowing gain modification through external resistance

Applications

• High-quality analog signal processing
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis
• Accurate voltage-controlled oscillators and filters

Procurement Notes

Verify component authenticity against MIL-PRF-38534 Class K specifications. Confirm that the specific suffix denotes space-qualified die requirements. Ensure environmental compliance matches project constraints. Validate package integrity upon receipt. Cross-reference datasheet revisions to confirm parameter consistency.

Selection Notes

Select this component when high-precision analog multiplication or division is required in harsh environments. The fully differential input architecture provides flexibility for complex signal processing tasks. Consider the adjustable scale factor for gain customization. Verify thermal management capabilities align with the specified operating temperature range.
