TDA8924
16.12 Curves measured in the reference design
ThecurvesillustratedinFigs 19 and 20aremeasuredwith
a restive load impedance. Spread in R
L
(e.g. due to the
frequency characteristics of the loudspeaker) can trigger
the maximum current protection circuit; see Section 16.6.
The curves illustrated in Figs 29 and 30 show the effects
of supply pumping when only one single-ended channel is
driven with a low frequency signal; see Section 16.7.
