AD2S82AJPZ

Overview

The AD2S82AJPZ is a resolver-to-digital converter manufactured by Analog Devices Inc. It converts analog resolver signals into digital position and speed data. The device operates on dual power supplies ranging from ±10.8 V to ±13.2 V, with a maximum power consumption of 300 mW. It features a parallel interface and is housed in a 44-PLCC package. The component supports variable resolution from 10 to 16 bits and includes an external reference type. It is designed for industrial applications with an operating temperature range of -55°C to +125°C.

Feature Summary

• Resolver-to-Digital conversion with 10 to 16-bit resolution
• Parallel data interface for direct microprocessor connection
• Wide operating temperature range: -55°C to +125°C
• Dual supply operation: ±10.8 V to ±13.2 V

Applications

• Industrial motor control systems
• Robotics position sensing
• CNC machine tool feedback loops

Procurement Notes

Verify current availability status as the part may be subject to limited supply or discontinuation. Confirm that the PLCC-44 package matches the target PCB footprint. Ensure the voltage requirements align with the system's dual power supply rails. Check for RoHS compliance documentation if required by specific manufacturing standards.

Selection Notes

Select this component when high-accuracy resolver feedback is needed in harsh environments. The wide temperature range suits automotive or outdoor industrial use. Compare resolution options (10-16 bit) against system precision requirements. Verify that the parallel interface timing meets the host controller's specifications.

Part Context

This part belongs to the AD2S82 family of resolver-to-digital converters. It shares functional similarities with variants like AD2S82AHPZ and AD2S82ALPZ, differing primarily in packaging and temperature grades. The AD2S82 series is designed for robust angular position measurement in demanding applications.

Replacement Considerations

Check for AD2S82AHPZ or AD2S82ALPZ as potential pin-compatible alternatives if package or temperature grade adjustments are acceptable. Verify electrical parameters match before substitution.
