AD2S82AJP

Overview

The AD2S82AJP is a resolver-to-digital converter manufactured by Analog Devices Inc. It operates within a supply voltage range of 10.8 V to 13.2 V and dissipates 300 mW of power. The device supports resolutions from 10-bit to 16-bit and features a parallel interface for data output. It is housed in a PLCC-44 package with J-bend terminals and is designed for surface-mount installation. The component functions as a single-channel converter, translating analog resolver signals into digital position data.

Feature Summary

• Resolver-to-Digital conversion capability
• Configurable resolution: 10-bit to 16-bit
• Parallel data interface
• PLCC-44 surface mount package

Applications

• Servo motor control systems
• Robotics joint positioning
• CNC machine tool axes

Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as supply constraints may apply. Confirm that the specific suffix 'JP' corresponds to the required commercial temperature grade and packaging format before ordering. Ensure compatibility with existing PCB footprints for the PLCC-44 package.

Selection Notes

Select this component when a dedicated hardware solution for resolver feedback is required without external microcontroller processing overhead. Verify that the system's excitation frequency falls within the supported range and that the parallel interface timing requirements match the host processor capabilities.

Part Context

This part belongs to the AD2S82A family of specialized data acquisition converters. It serves as a direct replacement for legacy synchronous resolver-to-digital designs, offering integrated signal conditioning and digital decoding in a single monolithic BICMOS circuit.

Replacement Considerations

Check for pin-compatible alternatives within the AD2S82 series, such as the AD2S82AHPZ, noting differences in temperature ratings and package variations. Ensure any substitute maintains the same 44-pin PLCC footprint and electrical specifications.
