AS5163 12-BIT PROGRAMMABLE MAGNETIC ROTARY ENCODER
2 Electrical Characteristics
2.1 Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings“ may cause permanent damage to the device. These are stress ratings
only. Functional operation of the device at these or any other conditions beyond those indicated under “Operating Conditions” is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
