Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 3:
Integral nonlinearity is defined as deviation of a code from a of a device may be impaired. straight line passing through the actual endpoints of the transfer curve.
Note 2:
All voltage values are with respect to GND. The deviation is measured from the center of the quantization band.
Note 4:
Channel leakage current is measured after the channel selection. 6
