... AD5303/AD5313/AD5323 TERMINOLOGY Relative Accuracy or Integral Nonlinearity (INL) For the DAC, relative accuracy or integral nonlinearity is a measure of the maximum deviation, in LSB, from a straight line passing through the actual endpoints of the DAC transfer function. A typical INL error vs. code plot can be seen in Figure 7, Figure 8, and Figure 9. ...

... POWER-DOWN MODES The AD5303/AD5313/AD5323 have very low power consump- tion, dissipating only 0.7 mW with supply and 1.5 mW with supply. Power consumption can be further reduced when the DACs are not in use by putting them into one of three power-down modes, which are selected by Bit 13 and Bit 12 (PD1 and PD0) of the control word ...

... COARSE AND FINE ADJUSTMENT USING THE AD5303/AD5313/AD5323 The DACs in the AD5303/AD5313/AD5323 can be paired together to form a coarse and fine adjustment function, as shown in Figure 45. DAC A provides the coarse adjustment while DAC B provides the fine adjustment. Varying the ratio of R1 and R2 changes the relative effect of the coarse and fine adjustments ...
