2. Offset_DAC: The Offset of a DAC is defined as the deviation between the measured and ideal output, when the DAC input is 01h. It is
expressed in LSB.
FSError_DAC: The Full Scale Error of a DAC is defined as the deviation between the measured and ideal output, when the input is FFh. It
is expressed in LSB. The Offset_DAC is subtracted from the measured value before calculating FSError_DAC.
DNL_DAC: The Differential Non-Linearity of a DAC is defined as the deviation between the measured and ideal incremental change in
the output of the DAC, when the input changes by one code step. It is expressed in LSB. The measured values are adjusted for Offset
and Full Scale Error before calculating DNL_DAC.
INL_DAC: The Integral Non-Linearity of a DAC is defined as the deviation between the measured and ideal transfer curves, after adjust-
ing the measured transfer curve for Offset and Full Scale Error. It is expressed in LSB.
