Note 1: All voltages with respect to ground. Currents entering the IC are specified positive, and currents exiting the IC are negative.  
Note 2: Supply current specified with all outputs set to zero current setting with all inputs (except A1 and A0, which can be open) driven  
to well-defined logic levels. SDA and SCL are connected to V . Excludes current through R resistors (I ). Total current

Note 3: The output-voltage full-scale current ranges must be satisfied to ensure the device meets its accuracy and linearity specifications.  
Note 4: Temperature drift excludes drift caused by external resistor.  
Note 5: Differential linearity is defined as the difference between the expected incremental current increase with respect to position  
and the actual increase. The expected incremental increase is the full-scale range divided by 31.  
Note 6: Integral linearity is defined as the difference between the expected value as a function of the setting and the actual value.  
The expected value is a straight line between the zero and the full-scale values proportional to the setting.

Note 7: Timing shown is for fast-mode (400kHz) operation. This device is also backward compatible with I C standard-mode timing.  
Note 8: C —total capacitance of one bus line in pF.
