Note 17: The ADC12041’s self-calibration technique ensures linearity and offset errors as specified, but noise inherent in the self-calibration process will result in

Note 18: Total Unadjusted Error (TUE) includes offset, full scale linearity and MUX errors.

Note 19: The ADC12041 parts used to gather the information for these curves were auto-calibrated prior to taking the measurements at each test condition. The

auto-calibration cycle cancels any first order drifts due to test conditions. However, each measurement has a repeatability uncertainty error of 0.2 LSB. See Note

17.

Note 20: The reference input current is a DC average current drawn by the reference input with a full-scale sinewave input. The ADC12041 is continuously con-

verting with a throughput rate of 206 kHz.

Note 21: These typical curves were measured during continuous conversions with a positive half-scale DC input. A 240 ns RD pulse was applied 25 ns after the

Note 22: Any other values placed in the command field are meaningless. However, if a code of 101 or 110 is placed in the command field and the CS , RD and WR

go low at the same time, the ADC12041 will enter a test mode. These test modes are only to be used by the manufacturer of this device. A hardware power-off and

power-on reset must be done to get out of these test modes.
