AD2S82AKPZ

Overview

The AD2S82AKPZ is a resolver-to-digital converter manufactured by Analog Devices Inc. It utilizes BICMOS technology and is housed in a 44-lead Plastic Leaded Chip Carrier (PLCC) package with J-bend terminals. The device operates on dual supply voltages ranging from ±10.8 V to ±13.2 V, typically centered at ±12 V. It supports a maximum tracking rate of 16.25 revolutions per second and achieves a maximum angular accuracy of 2 arc minutes. The component functions within a commercial temperature range of 0°C to 70°C and accepts input signal frequencies up to 20,000 Hz.

Feature Summary

• Resolver-to-Digital Conversion: Converts analog resolver signals into digital position data.

Procurement Notes

Verify the specific suffix 'KPZ' against current manufacturer documentation to confirm lead-free status and package variant. Check official Analog Devices channels for active manufacturing status, as older logic families may be subject to discontinuation or limited availability. Ensure compatibility with existing 44-PLCC footprints during procurement planning.

Selection Notes

Select the AD2S82AKPZ when high-accuracy resolver feedback is required for industrial motion control. Confirm that the application environment remains within the 0°C to 70°C commercial temperature range. Verify that the system power supplies can provide stable ±10.8 V to ±13.2 V rails. Ensure the host processor supports the parallel data interface timing requirements specified in the datasheet.

Part Context

This component belongs to the AD2S82 family of single-chip resolver-to-digital converters. It is designed to replace discrete solutions by integrating excitation generation, demodulation, and digital conversion into one BICMOS chip. The KPZ suffix denotes a specific plastic leaded chip carrier package configuration offered by Analog Devices for surface-mount assembly.

Replacement Considerations

Direct pin-compatible replacements within the same family include the AD2S82AJPZ and AD2S82ALPZ. Note that these variants differ primarily in operating temperature ranges and packaging materials rather than core electrical performance. Verify thermal requirements before substituting.
