AD2S46TD14B

Overview

The AD2S46TD14B is a resolver-to-digital converter manufactured by Analog Devices Inc. It features a 16-bit resolution and operates within an extended industrial temperature range of -55°C to +125°C. The device utilizes a 28-CDIP package with through-hole mounting. It provides a single channel for converting analog resolver signals into digital position data, suitable for high-reliability applications requiring precise angular measurement.

Feature Summary

• Converts analog resolver excitation and feedback signals into digital sine/cosine outputs
• Provides 16-bit resolution for high-precision angular position tracking
• Operates reliably in extreme environmental conditions across the full industrial temperature spectrum

Applications

• Servo motor control systems
• Robotics joint positioning
• Aerospace actuator feedback loops

Procurement Notes

Verify the specific suffix 'TD14B' against the official Analog Devices datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides valid traceability documentation for components intended for aerospace or industrial use. Confirm RoHS compliance status as listed in the manufacturer's current product announcements prior to finalizing orders.

Selection Notes

Select this component when a dedicated hardware solution for resolver signal conditioning is required without external microcontroller processing overhead. The through-hole CDIP package offers mechanical robustness for vibration-prone environments. Consider thermal management requirements given the wide operating temperature range and ensure the system design supports the necessary excitation frequencies specified in the technical documentation.

Part Context

This part belongs to the AD2S46 family of resolver-to-digital converters designed for demanding industrial and military applications. It serves as a critical interface between rotary transformers (resolvers) and digital control systems, replacing older discrete solutions with a monolithic integrated circuit approach for improved accuracy and reduced board space.

Replacement Considerations

Consult Analog Devices documentation for direct cross-reference models such as the AD2S46 series variants. Verify pin compatibility and software register configurations if substituting with other R/D converters from the same manufacturer.
