bso Pro The information related to the outputs status is read and memorized at the end of the

O tecurrent pulse top. The acquisition time is 100 ms (typ.). No audible noise is generated in the

leprocess. As for SHORT TO GND / VS the fault-detection thresholds remain unchanged from

o 30 dB to 16 dB gain setting. They are as follows:TDA7563PD
