1For input and output current specifications, negative current is defined as coming out of (sourcing) the specified device pin.  
2Function is correct but parameters are not guaranteed outside the general limits (7 to 40 V).  
3When EN = high, EILAx = 100 × [( | ILAx | × RREF / 15 ) –1], with ILAx in mA and RREF in kΩ.  
4EIMLA = 100 × [ max ( | ILAx– ILA(AV) | ) / ILA(AV) ] , where ILA(AV) is the average current of all active outputs.
