B = 22 Hz to 20 kHz, AES brick wall, Rs =0 .
[6]
B = 22 Hz to 20 kHz, AES brick wall, independent of Rs.

Vi =Vi(max) = 0.5 V RMS.
14. Application information
14.1 Output power estimation (Stereo mode)
The output power, just before clipping, can be estimated using Equation 5:
(5)
Where,
VP = supply voltage (V)
RL = load impedance ()
RDSon = on resistance of power switch ()
Rs = series resistance of the output inductor ()
tw(min) = minimum pulse width(s) depending on output current (s)
fosc = oscillator frequency in Hz (typically 320 kHz)
The output power at 10 % THD can be estimated by:
where
Po(1) = 0.5 % and Po(2) =10%.
Figure 27 and Figure 28 show the estimated output power at THD = 0.5 % and
THD = 10 % as a function of supply voltage for different load impedances in stereo mode.
