SVR and output pin behavior (case 2: with turn-on diagnostic)
The information related to the outputs status is read and memorized at the end of the
current pulse top. The acquisition time is 100 ms (typ.). No audible noise is generated in the
process. As for short to GND / Vs the fault-detection thresholds remain unchanged from 26
dB to 16 dB gain setting. They are as follows:
Figure 8.
Concerning short across the speaker / open speaker, the threshold varies from 26 dB to
16 dB gain setting, since different loads are expected (either normal speaker's impedance
or high impedance). The values in case of 26 dB gain are as follows:
