Total harmonic distortion is measured at the bandwidth of 22 Hz to 20 kHz, AES brick wall. The maximum limit is guaranteed but may

not be 100 % tested.

14. Application information

14.1 Output power estimation (Stereo mode)

The output power, just before clipping, can be estimated using Equation 5:

(5)

Where,

The output power at 10 % THD can be estimated by:

where

Figure 26 and Figure 27 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.
