AD2S82ALP

Overview

The AD2S82ALP is a monolithic, variable-resolution tracking resolver-to-digital converter manufactured by Analog Devices Inc. Housed in a 44-lead J-leaded PLCC package, this BiMOS II device converts analog resolver signals into digital position and velocity data. It supports user-selectable resolutions of 10, 12, 14, or 16 bits. The component operates with a typical power consumption of 300 mW and features an external reference type. It provides parallel data output interfaces and includes specific functions such as COMPLEMENT and VCO outputs within the surface-mount package configuration.

Feature Summary

• Monolithic BiMOS II tracking R/D converter with ratiometric conversion capability
• User-selectable resolution options: 10, 12, 14, or 16 bits
• High maximum tracking rate up to 1040 RPS at 10-bit resolution
• Includes COMPLEMENT and VCO (Inter LSB) output functions

Applications

• DC brushless and AC motor control systems
• Numerical control of machine tools
• Robotics axis control applications
• General process control environments

Part Context

The AD2S82ALP belongs to the AD2S82A series, which also includes variants like the AD2S82ALPZ. The 'LP' suffix typically denotes the plastic PLCC package variant, distinguishing it from ceramic or other package types within the same functional family. This component serves as a specialized data acquisition converter for high-precision motion control tasks.

Replacement Considerations

The AD2S82ALPZ is a pin-compatible variant within the same AD2S82A family, offering identical electrical specifications but potentially differing in environmental compliance or packaging material details. Designers should verify temperature range and RoHS status when substituting between LP and LPZ suffixes.
