LM4871: Absolute Max Ratings of Vo1/Vo2

Part Number: LM4871

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,
Shinichi Yokota

    Hi Yokota-san,

    Usually it is OK for analog input amplifiers if there's an input signal with a similar range as to when it's being powered. You may see some of your input signal passing through feedback resistor Rf.
