LTC1196/LTC1198
ELECTRICAL CHARACTERISTICS Note 2:
All voltage values are with respect to GND.
Note 4:
Total unadjusted error includes offset, full scale, linearity,
Note 3:
Integral nonlinearity is defi ned as deviation of a code from a multiplexer and hold step errors. straight line passing through the actual endpoints of the transfer curve.
Note 5:
Channel leakage current is measured after the channel selection. The deviation is measured from the center of the quantization band.
