6 / 28 page  6 LTC1196/LTC1198 DY A IC ACCURACY VCC = 2.7V, VREF = 2.5V, fCLK = fCLK(MAX) as defined in Recommended Operating Conditions, unless otherwise noted. AC CHARACTERISTICS VCC = 2.7V, VREF = 2.5V, fCLK = fCLK(MAX) as defined in Recommended Operating Conditions, unless otherwise noted. The q denotes specifications which apply over the full operating temperature range. Note 1: Absolute maximum ratings are those values beyond which the life of a device may be impaired. 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. 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.
