AD532SD

Overview

The AD532SD is a monolithic, internally trimmed analog multiplier and divider manufactured by Analog Devices. It operates within an extended temperature range of -55°C to +125°C and guarantees a maximum multiplying error of ±1% at 25°C, with a total error not exceeding ±4% across the full operating temperature range. The device features differential X and Y inputs supporting a transfer function of (X1 − X2)(Y1 − Y2)/10 V. It utilizes a 14-lead side-brazed ceramic dual in-line package (D-14) and requires dual power supplies ranging from ±10 V to ±22 V.

Feature Summary

• Internally laser-trimmed for high accuracy without external components
• Differential X and Y inputs providing flexibility for algebraic computation
• Monolithic construction ensuring reliability and reduced system size
• Capable of multiplication, division, squaring, and square rooting

Applications

• Multiplication and division operations
• Squaring and square rooting functions
• Algebraic computation systems
• Power measurements

Procurement Notes

Verify that the specific part number matches the required temperature grade and package type. Confirm RoHS compliance status if applicable to your manufacturing process. Ensure supply voltage ratings align with your system design before procurement. Check for any specific handling requirements related to the ceramic DIP package.

Selection Notes

Select the AD532SD when extended temperature operation between -55°C and +125°C is required. Choose this model over the J or K grades if higher temperature stability is necessary. Consider the D-14 ceramic package for robustness in harsh environments. Evaluate the need for differential inputs to maximize common-mode rejection capabilities.

Part Context

The AD532 series represents early pretrimmed monolithic multipliers designed to replace modular solutions. The SD variant specifically targets industrial and military applications requiring wide temperature tolerance. It serves as a direct replacement for older IC multipliers needing external trim networks, simplifying circuit design while maintaining precision performance.

Replacement Considerations

The AD532SD can directly replace other IC multipliers requiring external trim networks by grounding unused terminals. Verify pin compatibility with existing designs. Ensure supply voltage limits are respected during transition.
