6.3.1.2.1 Gain Overrange

Feedback resistor options at RFB pins include a gain overrange GOV in the nominal gain G. Gain overrange allows the post calibration system performance to have a full dynamic range with the correct gain. Use the full resolution N of the DAC90802 to maintain DNL performance with no missing codes for the overall system. All end-point code error specifications of DAC90802 in Section 5.5 are specified with overrange accounted for.
