Hello,
I cannot find the Absolute Max Ratings of LM4871's Vo1/Vo2 in the data sheet, however, how does the LM4871 behave if a voltage is externally applied to these pins when a supply to the LM4871 is turned off? Could it damage?
A voltage of about 2.5 VP-P can be applied between the Vo1 and Vo2 when it's turned off in the system.
Best regards,
