AD534KH/+

Overview

The AD534KH/+ is a monolithic, laser-trimmed four-quadrant analog multiplier and divider manufactured by Analog Devices Inc. It features differential, high-impedance inputs for X, Y, and Z channels, enabling flexible signal processing without external trimming components. The device guarantees a maximum multiplication error of ±0.25% and includes an internally trimmed scale factor of 10.00 V, adjustable via an external resistor. Designed for military-grade reliability, it operates within a temperature range of -55°C to +125°C and utilizes low-noise design techniques with excellent long-term stability.

Feature Summary

• Monolithic construction with laser-trimmed accuracy eliminating the need for external calibration
• Fully differential, high-impedance inputs on all channels including the Z-input
• Adjustable scale factor allowing gain reduction from the standard 10V to lower values
• Low noise performance with excellent supply rejection and long-term stability

Applications

• High-quality analog signal processing
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis
• Wideband, high-crest rms-to-dc conversion
• Accurate voltage controlled oscillators and filters

Procurement Notes

Verify the specific suffix KH/+ against official Analog Devices documentation to confirm military qualification status and package configuration. Ensure compatibility with required operating temperatures and input configurations before procurement. Cross-reference datasheet revisions to confirm current availability and manufacturing status.

Selection Notes

Select this component when high precision and differential input flexibility are required for analog computation tasks. Consider its military temperature rating and internal trimming capabilities for applications demanding stability without external adjustment circuits. Evaluate power supply requirements and noise specifications against system constraints.

Part Context

The AD534 series represents a family of precision analog multipliers known for their monolithic integration and high accuracy. This specific variant targets demanding environments requiring robust performance and minimal external component count. It serves as a core building block for complex signal processing systems where traditional hybrid solutions were previously necessary.

Replacement Considerations

Check for direct pin-compatible alternatives within the AD534 family or newer generations from Analog Devices. Verify that any substitute maintains the four-quadrant operation, differential input structure, and similar error specifications.
