DAC43608: Total error

Takashi Yamaguchi

Part Number: DAC43608

Hi team,

I received following question from my customer. Could you support the question below?

Is the total error of the DAC43608 offset error + Gain error + INL + DNL ? Or is there another specification as total error?

Regards,

Yamaguchi

Hi Yamaguchi-san,

The total unadjusted error or TUE including the reference is given by the root-square-sum of the

1. Offset error

2. Gain error

3. INL

4. Reference accuracy

Hope that answers your question.

Hi Uttam-san,

Thank you for your support.

Could you let me know the allowable range of TUE for proper operation?

Regards,

Yamaguchi

Yamaguchi-san,

I may not understand the question, but, TUE is not an input - so there isn't some allowed range for functionality of the DAC. Instead, the TUE is simply a figure of merit concerning the accuracy of the DAC output, calculated based on the root-sum-squared calculation of the components Uttam mentioned.
