AD2S82AKPZ-REEL

Overview

The AD2S82AKPZ-REEL is a resolver-to-digital converter from Analog Devices, part of the AD2S82A family. It converts analog sine and cosine signals from a resolver into digital position data with selectable resolutions of 10, 12, 14, or 16 bits. The device operates on dual supplies ranging from ±10.8 V to ±13.2 V and features a parallel digital interface. It is housed in a 44-PLCC package and supports high tracking rates up to 16.25 rps with an angular accuracy of 2 arc minutes.

Feature Summary

• Resolver-to-Digital conversion with selectable resolution (10/12/14/16 bit)
• Parallel digital output interface
• High tracking rate capability up to 16.25 revolutions per second
• Angular accuracy of 2 arc minutes

Applications

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

Procurement Notes

Verify availability status as distribution channels may indicate limited supply or discontinuation for specific suffixes like REEL. Confirm moisture sensitivity level (MSL 3) and reflow soldering profile requirements before procurement. Ensure the supplier provides valid traceability documentation for this specialized data acquisition component.

Selection Notes

Select this model when a parallel interface is required for high-speed resolver feedback. Compare against AD2S82AHPZ if a tube package is preferred over reel packaging. Verify that the system power supply can provide stable ±10.8 V to ±13.2 V rails, as the device requires dual supplies for operation.

Part Context

This component belongs to the AD2S82A series of variable-resolution single-chip resolver-to-digital converters. It shares core architecture with variants such as AD2S82ALPZ and AD2S82AHPZ, differing primarily in packaging (PLCC vs. LCC) and shipping format (Reel vs. Tube). The 'K' suffix typically denotes a specific temperature grade or package variant within the manufacturer's lineup.

Replacement Considerations

Direct pin-compatible replacements include other AD2S82A family members like AD2S82ALPZ or AD2S82AHPZ, provided the packaging difference (Reel vs. Tube) is acceptable for the assembly process. Cross-referencing with AD2S80A or AD2S81A may require interface adjustments due to different resolution capabilities or pin configurations.
