| VSCALE | INL (3) | - | -1.6 | 0.75 | 1.6 | LSB |
| DNL (3) | - | -0.95 | 0.25 | 0.95 | LSB | |
| Offset Error (1,2) | - | -0.2 | 0.26 | 1.04 | LSB | |
| Gain Error (1,2) | - | -0.89 | 0.215 | 2 | LSB |
Note:
- According to the standard equation, V(X) = VLSB*(X+1); VLSB = VDDANA/64.
- Data computed with the Best Fit method.
- Data computed using histogram.
