Stresses exceeding these “Absolute Maximum Ratings” may cause permanent damage to the device. These are

stress ratings only. Functional operation at these or any other conditions beyond those indicated under “Acoustic

& Electrical Specifications” is not implied. Exposure beyond those indicated under “Acoustic & Electrical

Specifications” for extended periods may affect device reliability.
