AD2S80ASE/883B

Overview

The AD2S80ASE/883B is a single-chip resolver-to-digital converter manufactured by Analog Devices Inc. It converts the electrical signals from a resolver into digital position data. The device operates within a temperature range of -55°C to +125°C and utilizes a ceramic LCC-28 package. Key electrical specifications include a maximum tracking rate of 16.25 revolutions per second and a maximum angular accuracy of 4 arc minutes. It functions with supply voltages typically ranging from 10.8 V to 13.2 V for positive rails and -12 V for negative rails, supporting signal frequencies up to 20 kHz.

Feature Summary

• Single-chip architecture integrating resolver-to-digital conversion capabilities
• High precision with a maximum angular accuracy of 4 arc minutes
• Supports high-speed operation with a maximum tracking rate of 16.25 rps
• Military-grade qualification indicated by the /883B suffix

Applications

• Precision servo motor control systems
• Aerospace navigation and attitude determination
• Industrial robotics joint positioning
• Radar antenna stabilization platforms

Procurement Notes

Verify component authenticity due to military specification requirements. Confirm lot traceability and test reports are available. Check for lead time constraints as this is a specialized analog component. Ensure storage conditions meet moisture sensitivity level requirements for ceramic packages.

Selection Notes

Select this model when high angular accuracy and wide temperature operation are required. Compare against AD2S80 variants if lower cost or commercial temperature ranges suffice. Verify pin compatibility with existing PCB layouts as it uses an LCC-28 package. Ensure power supply rails match the specified 12V and -12V requirements.

Part Context

This part belongs to the AD2S80 family of resolver-to-digital converters. The /883B suffix denotes compliance with MIL-PRF-38534 standards for hybrid microcircuits. It serves as a critical interface between mechanical rotational sensors and digital processing units in harsh environments.

Replacement Considerations

Direct replacements include other AD2S80 family members such as AD2S80AJD or AD2S80ABD, provided pinouts and performance specs align. Verify that alternative parts meet the same military qualification standards if required by the application.
