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.

Note 1: All devices are 100% production tested at T
A
= +25°C. All temperature limits are guaranteed by design.
Note 2: Operating within the recommended supply voltage range ensures that negative audio signals are not limited by the device.
Supply voltages above the recommended supply voltage range may limit the headphone amplifier’s maximum output voltage.
Note 3: Supply current is measured when switches are off.
