TDA8920B

2

× 100 W class-D power amplifier

In case of an impedance drop (e.g. due to dynamic behavior of the loudspeaker) the same

protection will be activated; the maximum output current is again limited to 8 A, but the

amplifier will NOT switch-off completely (thus preventing audio holes from occurring).

Result will be a clipping output signal without any artefacts.

See also Section 13.6 for more information on this maximum output current limiting

feature.
