Ω; f = 1KHz;

(*) Saturated square wave output

(**) see figure 5 for THD setting.

The TDA7376PD is equipped with a programmable clipping distortion detector circuitry that allows to sig-

nal 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 desired threshold is

fixed through an external divider that produces a proper voltage level across the THD set pin. Fig. 4 shows

the THD detection threshold versus the THD set voltage. Since it is essential that the THD set voltage be

computed by multiplying the fraction corresponding to the desired THD threshold by the application’s sup-

ply voltage.
