... AD5627R/AD5647R/AD5667R, AD5627/AD5667 TERMINOLOGY Relative Accuracy or Integral Nonlinearity (INL) For the DAC, relative accuracy or integral nonlinearity is a measurement of the maximum deviation, in LSBs, from a straight line passing through the endpoints of the DAC transfer function. Differential Nonlinearity (DNL) Differential nonlinearity is the difference between the measured change and the ideal 1 LSB change between any two adjacent codes. A specified differential nonlinearity of ± ...

... AD5627R/AD5647R/AD5667R, AD5627/AD5667 POWER-ON RESET AND SOFTWARE RESET The AD56x7R/AD56x7 contain a power-on reset circuit that controls the output voltage during power-up. The device powers and the output remains powered up at this level until a valid write sequence is made to the DAC. This is useful in applications where it is important to know the state of the output of the DAC while the process of powering up ...
