Notes:

1

The op amp limits the linearity for V

output voltage remains above 100mV, then the linearity specifications apply to all codes. For V

GND, V

and differential linearity are computed with respect to the best fit straight line through codes 8

through 255.

2

SP9841 is measured between adjacent channels, f = 100kHz; SP9842 is measured between

adjacent pairs, f = 100kHz.
