Figure 21. 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 / V
26 dB to 12 dB gain setting. They are as follows:TDA7563A
