ELECTRICAL CHARACTERISTICS (Refer to the test circuit, V
R
*: The output average power when the amplifier is playing music can be considered roughly 1/10 of the maximum output power. So it is useful
**: P
***: The zero-signal switching frequency can be obtained using the following expression: F
****: The maximum value of R
(1): For V
f
to consider the dissipated power in this condition for thermal dimensioning.
