LMP8645: Absolute maximum rating of differential voltage

Guru 19485 points
Part Number: LMP8645

LMP8645 datasheet is described absolute max rating of +Vin - (-Vin), but only max: 6V. 

Please let me know about Min voltage range.

I think that min voltage range is a little negative voltage, for example -0.3V, correct?

Or, is 0V correct?

Best regards,


  • Hi Satoshi,

    A zero or slightly negative input differential voltage should definitely be OK and will not harm the device. If I interpret this datasheet paragraph correctly, the max rating should be ±6V:

    BTW, under what circumstances do you anticipate a negative input?

    Regards, Guang
