Table 4. System Characteristics (Continued)
1. The relative linearity is defined as the difference of the minimum to the maximum gain over the entire REFIN
2. The absolute linearity is defined as the actual gain error (AE) of every applied V
3. The ripple voltage should measured at C
4. For dynamic change in V
5. V
