Definition of Specifications

Differential Non-Linearity (DNL) is the measure of the step

size output deviation from code to code. Ideally the step size

should be one LSB. A DNL specification of one LSB or less

guarantees monotonicity.

Integral Non-Linearity (INL) is the measure of the worst

case point that deviates from a best fit straight line of data

values along the transfer curve.

Full Scale Gain Drift is measured by setting the DAC inputs

to be all logic high (all 1’s) and measuring the output voltage

through a known resistance as the temperature is varied
