Definition of DAC INL
The INL calculation returns 2
the DAC (the number of bits). A DAC INL test checks the
maximum of these values against a given limit to determine the
pass/fail result.
Integral Non-Linearity can be calculated using the end-point method, zero-
point method, or minimum root mean square method. All three methods use
the same formula. Only the definition of the DeviceLSB and Vref varies from
method to method.
The DeviceLSB is calculated as for the DNL measurement.
Calculation of DAC INL
Like for the DNL measurement, the software provides three
calculation methods: End point, zero-point, and minimum rms.
The DeviceLSB is calculated as for the corresponding DNL
measurement. The reference voltage V
