AD2S44UM12

Overview

The AD2S44UM12 is a monolithic synchronous resolver-to-digital converter manufactured by Analog Devices Inc. It integrates two complete channels for simultaneous position and velocity tracking, designed for high-performance servo applications. The device operates with a nominal supply voltage of plus or minus 15 volts and features a metal dual in-line package (MDIP) with 32 pins. It provides digital outputs representing angular position and rotational speed derived from analog resolver signals.

Feature Summary

• Integrates two independent tracking channels for simultaneous position and velocity processing
• Includes built-in test circuitry for system verification and diagnostics
• Accepts a wide range of reference input voltages up to 26 volts
• Delivers high angular resolution suitable for precision motion control systems

Applications

• High-precision industrial servo motor control loops
• Robotics joint positioning and orientation feedback
• Aerospace actuator position sensing systems
• CNC machine tool axis tracking

Procurement Notes

Verify the specific suffix UM12 against official Analog Devices documentation to confirm pinout compatibility and temperature grade. Ensure the procurement channel provides traceable component history. Confirm that the MDIP-32 package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when dual-channel resolver feedback is required within a single integrated circuit. It is appropriate for designs needing high accuracy without external signal conditioning. Consider the metal package thermal properties and board space constraints associated with the MDIP form factor during layout planning.

Part Context

This part belongs to the AD2S44 family of resolver-to-digital converters. These devices are engineered to replace discrete logic solutions, reducing board space and improving reliability. The family supports various packaging options including plastic DIP and ceramic packages to suit different environmental and cost requirements.

Replacement Considerations

Check for direct cross-references such as the AD2S44TM18B which shares similar functional characteristics. Verify pin compatibility and electrical specifications before substituting any alternative models to ensure system integrity.
