AD5669R, accuracy vs offset error

Hi there,

 

I am a bit confused about the offset error and the accuracy of the DAC AD5569R. The value of the LSB should be 5 / (2^16) = 76 uV. So according to the datasheet, page 3 the accuracy is 8*LSB = 0,6 mV. But the offset error is 6 mV. Why do you need such a high accuracy, if the error is that high? I need an output of that accuracy, but I can't use it because of the offset error. Or can I?

 

Regards,

Elena
