AD2S44TM18

Overview

The AD2S44TM18 is a synchronous resolver-to-digital converter manufactured by Analog Devices Inc. It converts analog sine and cosine signals from a resolver or synchro into parallel digital position data. The device features a 14-bit resolution with a maximum angular accuracy of 4 arc minutes. It operates within an extended temperature range of -55°C to +125°C and utilizes a metal dual in-line package (MDIP) with 32 pins. Key electrical specifications include a 26V reference input capability and supply voltages nominally at ±15V.

Feature Summary

• 14-bit parallel digital output for high-resolution position sensing
• Maximum angular accuracy of 4 arc minutes
• Built-in test functionality for system verification
• Supports both synchro and resolver inputs

Applications

• Precision motor control systems
• Robotics joint positioning
• Aerospace actuator feedback

Procurement Notes

Verify the RoHS compliance status, as listed parameters indicate non-compliance. Confirm the specific suffix 'TM18' against official Analog Devices documentation to ensure correct temperature grade and packaging variant. Check lead content requirements if applicable to your manufacturing standards.

Selection Notes

Select this component when 14-bit resolution and 4 arc minute accuracy are required for resolver interfaces. Ensure the application supports the MDIP-32 package dimensions and the ±15V power supply rails. Verify compatibility with the 26V reference input voltage range.

Part Context

This part belongs to the AD2S44 family of resolver-to-digital converters. It is designed for applications requiring reliable conversion of analog angular positions into digital words. The TM18 suffix typically denotes specific thermal and mechanical characteristics within the product line.

Replacement Considerations

Consult Analog Devices datasheets for direct pin-compatible alternatives within the AD2S4x series. Verify that any substitute maintains the 14-bit resolution and 4 arc minute accuracy specification.
