All typical values are at TA = 25°C.
NOTES: 6. Linear error is the maximum deviation from the best fit straight line through the A/D transfer characteristics.
7. Bipolar zero error is the difference between 100000000000 and the converted output for zero input voltage; positive full-scale error
is the difference between 111111111111 and the converted output for positive full-scale input voltage (10 V); negative full-scale error
is the difference between 000000000000 and the converted output for negative full-scale input voltage (−10 V).
8. It is measured by applying a full-scale of 35 kHz signal to other channels and determining how much the signal is attenuated in the
channel of interest. The converter samples this examined channel continuously. The channel-to-channel isolation is degraded if the
converter samples different channels alternately.
