Hi team
Here is a question we do not find the answer in the datasheet:
When the microphone input signal of the PMC6340Q1 chip is shorted to 18V battery, the MICBIAS voltage of the chip will be raised.
I know the normal programmable voltage value will up to 9V, while in the case above I do not know what MICBIAS voltage value will raise,
Please confirm the maximum voltage that the MICBIAS voltage can withstand all the time, it is not marked in SPEC, it will be used for customer WCA analysis, thank you.
