Hi,
I'm using the TAS2781EVM to test the Beep Generator feature of the TAS2781 using the SDZ pin. No software is running on the PC, just power and the SDZ signal is applied.
Applying 55 kHZ and 50% duty cycle to the SDZ pin starts the beep generation as expected, but it stops after 50 ms despite the PWM is still active. Generating several beeps in a row with a burst signal is possible and shorter beeps can also be created. But I can not get past the max. length of ca. 50 ms what is not expected according to the datasheet.
CH1: SDZ pin
CH2: OUTP pin
Please advise.
