5 / 36 page Audio Subsystem with Mono Class D Speaker and Class H Headphone Amplifiers 5 Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. (Voltages with respect to GND.)
