6. Electrical Characteristics

6.1 Absolute Maximum Ratings (Non-Operating)

Stresses beyond the ‘Absolute Maximum Ratings’ may cause permanent damage to the AS8218 / AS8228 ICs.

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.

Caution: Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
