Note 3: Integral nonlinearity is defi ned as deviation of a code from a
straight line passing through the actual endpoints of the transfer curve.
The deviation is measured from the center of the quantization band.
Note 4: Channel leakage current is measured while the part is in sample
mode.
Note 5: Guaranteed by design, not subject to test.
