AD2S82ALPZ

Overview

The AD2S82ALPZ is a single-channel resolver-to-digital converter (RDC) manufactured by Analog Devices Inc. It integrates variable resolution capabilities ranging from 10 to 16 bits within a single chip. The device utilizes a parallel data interface and operates on dual power supplies between ±10.8 V and ±13.2 V, with a maximum power consumption of 300 mW. Housed in a 44-PLCC surface-mount package, it supports signal frequencies up to 20 kHz and offers a tracking rate of 16.25 revolutions per second. The component is designed for commercial temperature ranges from 0°C to +70°C.

Feature Summary

• Variable resolution architecture supporting 10, 12, 14, or 16-bit outputs
• High angular accuracy with a maximum error of 2 arc minutes
• Parallel digital interface for direct system integration
• Single-chip implementation eliminating external logic requirements

Applications

• Precision motor control systems
• Servo drive position feedback
• Robotics joint angle sensing
• CNC machine tool positioning

Procurement Notes

Availability for the AD2S82ALPZ is currently restricted. Major distributors such as Mouser and DigiKey list the part as discontinued or out of stock with no backorder capability. Verification of current supply status through official Analog Devices channels is required before procurement planning.

Selection Notes

Select this component when a high-accuracy, single-channel RDC with parallel output is required. Ensure the application environment remains within the commercial temperature range of 0°C to +70°C. Verify that the system can accommodate the ±10.8 V to ±13.2 V dual supply rails and the 44-pin PLCC footprint constraints.

Part Context

This part belongs to the AD2S82A family of resolver-to-digital converters. It shares core specifications with variants like the AD2S82AHPZ but differs in packaging and temperature rating. The AD2S82 series provides an alternative to discrete synchro/resolver solutions by integrating excitation generation and demodulation functions.

Replacement Considerations

The AD2S82AHPZ is a related variant within the same product family. Both share identical electrical specifications and pinouts. Selection between them depends primarily on package availability and specific temperature grade requirements.
