AD534KHZ

Overview

The AD534KHZ is a monolithic, laser-trimmed four-quadrant analog multiplier and divider manufactured by Analog Devices Inc. It operates within the military temperature range of -55°C to +125°C and utilizes a TO-100-10 metal can package. The device guarantees a maximum multiplication error of ±0.25% without external trimming. It features fully differential, high-impedance inputs for X, Y, and Z terminals. The internal scale factor is pretrimmed to 10.00 V but can be adjusted via an external resistor to values as low as 3 V.

Feature Summary

• Monolithic construction with laser trimming for high precision
• Four-quadrant operation with fully differential inputs
• Internal thin-film resistors and buried Zener reference for stability

Applications

• High-quality analog signal processing
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis
• Accurate voltage-controlled oscillators and filters

Procurement Notes

Verify component authenticity through authorized channels due to military-grade specifications. Confirm package integrity for the TO-100-10 metal can format. Check for RoHS compliance status relative to specific procurement requirements. Ensure handling procedures account for the sensitivity of the internal thin-film structures. Validate that the operating environment remains within the specified -55°C to +125°C range.

Selection Notes

Select this component when high accuracy and long-term stability are required in harsh environments. The fully differential input architecture offers flexibility for complex signal processing tasks. Consider the adjustable scale factor for gain configuration needs. Evaluate the need for military temperature rating against cost constraints. Compare performance metrics with other quadrants multipliers if standard industrial ranges suffice.
