AD539SD/883B

Overview

The AD539SD/883B is a four-quadrant analog multiplier integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of ±4.5 V to ±18 V and draws a maximum quiescent current of 10 mA. The device supports an input frequency bandwidth of up to 2 MHz and achieves a typical settling time of 1 µs. It provides a full-scale output voltage swing of ±10 V and maintains a DC accuracy of 0.1%. The component is housed in a 20-lead Ceramic Leadless Chip Carrier (CLCC) package and is qualified for military and aerospace environments, functioning reliably across an operating temperature range of -55°C to +125°C.

Feature Summary

• Provides precise four-quadrant analog multiplication capabilities with high DC accuracy.
• Features wide signal bandwidth supporting frequencies up to 2 MHz.
• Includes internal compensation circuits to minimize external component requirements.
• Designed for rugged operation in extreme environmental conditions.

Applications

• Automatic gain control systems
• Frequency modulation and demodulation circuits
• Phase-locked loops
• Analog computation units

Procurement Notes

Verify the specific suffix /883B indicates Mil-Aero qualification when sourcing. Confirm the CLCC-20 package compatibility with your PCB footprint. Check for RoHS status as military variants often differ from commercial standards. Ensure the supplier provides traceability documentation required for aerospace or defense contracts. Validate that the operating temperature range meets your system's thermal constraints.

Selection Notes

Select this component when high-speed analog multiplication is required alongside strict environmental durability. Compare against commercial counterparts if military certification is unnecessary. Consider the 20-lead CLCC package size relative to available board space. Evaluate the ±10 V output swing against your downstream amplifier input limits. Verify power supply rejection ratios if noise-sensitive applications are involved.

Part Context

This part belongs to the AD539 family of analog multipliers, designed for precision signal processing. The /883B suffix denotes compliance with MIL-PRF-38534 specifications for hybrid microcircuits. It serves as a robust alternative to standard commercial multipliers in harsh environments. The device integrates essential biasing and compensation internally to simplify circuit design.
