* Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.
‡ Typical figures are at 25°C and are for design aid only.
Note 1: All of the above test conditions use a test source impedance which matches the device’s impedance.
Note 2: THD is measured with “A Weight” filter.
