The ADAU1450 datasheet on page 6 says that the DVDD current in reset is 20 mA Typical and 95 mA Max. Is this correct, or should it be uA?

Hello pbthesp,

I know this seems strange at first glance but it is because of the way we have to guard band and account for all silicon skew corners. For "fast" parts there is a lot more leakage and we have to cover that unlikely case in the datasheet. This is an automotive qualified part so we have to setup a larger margin for outliers. For nominal silicon it does not have much leakage, that is the "typical number" but it is in mA. I have been measuring this in the lab for another customer for the past several weeks so I can verify this is correct.

Hello Dave,

Thank you for confirming that.
