AD532SD/883B

Overview

The AD532SD/883B is a pretrimmed, monolithic analog multiplier and divider manufactured by Analog Devices. It operates within a temperature range of -55°C to +125°C and utilizes a 14-lead side-brazed ceramic dual in-line package (D-14). The device guarantees a maximum multiplying error of ±1% at 25°C and ±4% across the full operating temperature range. It features differential X and Y inputs with a transfer function of (X1 − X2)(Y1 − Y2)/10 V. Key electrical specifications include a small-signal bandwidth of 1 MHz, a slew rate of 45 V/μs, and a settling time of 1 μs to 2%. The quiescent supply current is typically 6 mA.

Feature Summary

• Internally laser-trimmed for high accuracy without external components
• Monolithic construction providing reliability and compact size
• Differential X and Y inputs for enhanced noise rejection and computational flexibility

Applications

• Multiplication, division, squaring, and square rooting operations
• Algebraic computation and power measurements
• Instrumentation applications requiring transducer signal processing
• Trigonometric calculations for airborne navigation and guidance systems

Procurement Notes

Verify that the specific part number AD532SD/883B corresponds to the military-grade variant with extended temperature ratings (-55°C to +125°C) and hermetic sealing. Confirm compliance with MIL-STD-883 requirements if applicable. Ensure the D-14 side-brazed ceramic package matches the design footprint. Check for RoHS status implications if integrating into modern assemblies.

Selection Notes

Select this component when high precision and wide temperature stability are required for analog signal processing. The internal trimming eliminates the need for external calibration networks, simplifying circuit design. Consider the 1 MHz bandwidth and low offset voltage for high-speed or sensitive measurement applications. Verify that the differential input configuration aligns with the system's signal source characteristics.

Part Context

The AD532 series represents a family of internally trimmed monolithic multipliers/dividers. The SD/883B designation indicates the specific grade optimized for harsh environments, offering guaranteed performance over an extended industrial/military temperature range compared to standard commercial variants.

Replacement Considerations

The AD532 can serve as a direct pin-for-pin replacement for other IC multipliers requiring external trim networks by grounding unused terminals. No other specific substitute part numbers are confirmed in the provided documentation.
