AD532KH

Overview

The AD532KH is a pretrimmed, single-chip monolithic analog multiplier and divider manufactured by Analog Devices. It guarantees a maximum multiplying error of ±1.0% at 25°C with a transfer function of (X1 − X2)(Y1 − Y2)/10 V. The device operates on dual supplies ranging from ±10 V to ±18 V and features differential inputs for high common-mode rejection. It supports multiplication, division, squaring, and square rooting functions without requiring external trimming components.

Feature Summary

• Internally laser-trimmed to guarantee ±1.0% maximum four-quadrant multiplying error
• Differential X and Y inputs provide high common-mode rejection and computational flexibility
• Monolithic construction eliminates the need for external trimming resistors or output operational amplifiers

Applications

• Multiplication, division, squaring, and square rooting operations
• Algebraic computation and trigonometric calculations
• Power measurements and transducer instrumentation
• Airborne navigation and guidance systems

Procurement Notes

Verify the specific suffix 'H' against the official Analog Devices ordering guide to confirm package type and temperature range specifications. Ensure compatibility with required supply voltages and signal ranges before integration. Confirm RoHS compliance status if applicable to your manufacturing standards. Cross-reference pin configurations for both D-14 and H-10 packages during schematic design.

Selection Notes

Select the AD532KH when a guaranteed ±1.0% total error at 25°C is required for precision applications. Choose this component over modular multipliers to reduce system size and complexity due to its monolithic design. Consider the differential input capability for noise-sensitive environments where high common-mode rejection is critical for accurate signal processing.

Part Context

The AD532 series represents the first pretrimmed, single-chip monolithic multiplier/divider from Analog Devices. It offers significant advantages in reliability and economy compared to hybrid approaches. The device integrates all necessary components for self-contained operation, including an internal operational amplifier, simplifying circuit design for engineers.

Replacement Considerations

The AD532 can serve as a direct replacement for other IC multipliers that require external trim networks. For pin-for-pin replaceability, ground the X2, Y2, and VOS terminals when replacing legacy designs.
