Absolute Maximum Ratings 1, 2 Notes: 1. Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is stress r ating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this s pecification is not implied. 2. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 3. This device meets the ESD ratings of the IEC61000-4-2 Level 2 (4KV). Recommended Operating Conditions Notes: 1. As unique coded gear-wheels techniques are implemented to generate unambigous positional information, the interactions between these highly wear- resistant gear wheels are subjected to mechanical wear and tear.
