ELECTRICAL CHARACTERISTICS
Note 2: All voltage values are with respect to GND.
Note 3: Integral nonlinearity is defined 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.
LTC1196/LTC1198
Note 4: Total unadjusted error includes offset, full scale, linearity,
multiplexer and hold step errors.
Note 5: Channel leakage current is measured after the channel selection.
