I1 Undershoot On D/a Converter Data Byte
Transition
DAC input byte changing from 00h to
FFh and vice versa, V(I1) is V_CC - 1.2V
in source mode and 1.2V in sink mode.

divided by the resistance between R₁ or R₂ to Vss.
6. 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 adjusting the
measured transfer curve for Offset and Full Scale Error. It is expressed in LSB.
7. These parameters are periodically sampled and not 100% tested.
