(*) Saturated square wave output
(**) see figure 5 for THD setting.
The TDA7376B is equipped with a programmable
clipping distortion detector circuitry that allows to
signal out the output stage saturation by providing
a current sinking into an open collector output
(DDout) when the total harmonic distortion of the
output signal reaches the preset level. The de-
sired threshold is fixed through an external divider
that produces a proper voltage level across the
THD set pin. Fig. 5 shows the THD detection
threshold versus the THD set voltage. Since it is
essential that the THD set voltage be proportional
to the supply voltage, fig. 5 shows its value as a
fraction of VCC. The actual voltage can be com-
puted by multiplying the fraction corresponding to
the desired THD threshold by the application’s
supply voltage.
