Note 2: Averaged measurements assume dithering and averaging of 100 single-channel readings.

Relative accuracy is defined as the measured deviation from a straight line drawn between measured endpoints

of the transfer function. ADC resolution, noise and front-end non-linearity are included in this measurement.
