How to caculate the total output errors of AD8304?

Hi,

     I want to use AD8304 to design a device to accurately measure  optical power from  a photodiode , so I have to caculate the theory errors of the output of AD8304 first. But apart from the log conformance error,I didn't find anything else to do this. No data about typical input bias current or gain errors . In Ti's

LOG114 datasheet, there is a method to  caculate the total output errors,not just a log conformance error in dB.By the way, how to transform 0.1 dB log conformance error into Vlog output error in percent?

 

Thanks,

Eason
