AD534TE/883B

Overview

The AD534TE/883B is a monolithic, laser-trimmed four-quadrant analog multiplier and divider manufactured by Analog Devices Inc. It operates within a military temperature range of -55°C to +125°C and utilizes a CLCC-20 package. The device features fully differential, high-impedance inputs for X, Y, and Z channels, ensuring flexibility in signal processing applications. It includes an on-chip thin-film resistor network and buried Zener reference for long-term stability. The scale factor is pretrimmed to 10.00 V, with external adjustment capabilities.

Feature Summary

• Monolithic construction with internal laser trimming for precision performance
• Fully differential, high-impedance operation on all input channels
• Integrated thin-film resistors and buried Zener reference for stability
• Adjustable scale factor via external resistor connection

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 /883B indicates compliance with MIL-PRF-38534 Class K requirements for space-qualified die. Confirm that the component matches the exact pinout and electrical specifications of the standard AD534L variant before integration. Ensure supply chain sources provide valid traceability documentation for military-grade components.

Selection Notes

Select this component when high accuracy and long-term stability are required in harsh environments. The differential input architecture simplifies circuit design by eliminating common-mode noise issues. Consider the adjustable scale factor for gain flexibility. Verify thermal management requirements for the CLCC-20 package within the specified operating temperature range.

Part Context

This part belongs to the AD534 series of precision analog multipliers. It shares core functionality with the AD534L but is qualified for extended military and aerospace conditions. The /883B suffix denotes specific packaging and qualification standards distinct from commercial variants. It serves as a foundational building block for complex mathematical operations in analog computing systems.
