ADW71205WSTZ

ADCs/DACs - Special Purpose Overview

The ADW71205WSTZ is a 12-bit Resolver-to-Digital (R/D) converter manufactured by Analog Devices Inc. It operates on a single 5V supply and supports both parallel and serial digital interfaces. The device provides high-precision angular position data with an accuracy of ±22 arcminutes and a typical tracking rate of 750 revolutions per second (rps). Housed in a 44-LQFP package measuring 10x10 mm, it is qualified under the AEC-Q100 standard for automotive applications and functions within a temperature range of -40°C to +125°C.

ADCs/DACs - Special Purpose Feature Summary

• 12-bit resolution with ±22 arcminute precision
• AEC-Q100 qualified for automotive reliability
• Supports parallel and serial output interfaces
• Operates on a single 5V power supply

ADCs/DACs - Special Purpose Applications

• Automotive steering angle sensing systems
• Electric vehicle motor control feedback
• Industrial servo drive position monitoring
• Robotics joint angle measurement

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'WSTZ' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Confirm that the required interface mode (parallel or serial) matches the system design, as the device supports both. Ensure the PCB footprint corresponds to the 44-LQFP (10x10 mm) dimensions specified in the official documentation.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 12-bit resolution resolver interface is required for automotive-grade environments. Compare the 750 rps tracking rate against the maximum mechanical speed of the target application. Consider the EVAL-AD2S1205SDZ development kit for initial circuit validation and signal integrity testing before final production integration.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD2S1205 family of R/D converters. It shares core specifications with variants such as the AD2S1205WSTZ and ADW71205YSTZ. The primary distinctions among these models typically involve packaging options (tray vs. reel) and specific automotive qualification grades, while maintaining identical electrical performance characteristics.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes include other parts from the AD2S1205 family, such as the AD2S1205WSTZ or ADW71205YSTZ. Verify that any replacement maintains the same 44-LQFP footprint and AEC-Q100 qualification if automotive compliance is mandatory.
