(*) Saturated square wave output
(**) see figure 5 for THD setting.
The TDA7376B is equippedwith a programmable
clipping distortion detector circuitry that allows to
signal out the output stagesaturation 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 thresholdis fixedthrough an externaldivider
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
essentialthat the THD set voltagebe proportional
to the supply voltage, fig. 5 shows its value as a
fraction of V
CC
. The actual voltage can be com-
puted by multiplying the fraction corresponding to
the desired THD threshold by the application’s
supplyvoltage.
