1 For
input and output current specifications, negative current is defined as coming out of (sourcing) the specified device pin.
2 Function is correct but parameters are not guaranteed outside the general limits (7 to 40 V).
3 When EN = high, E ILAx = 100 × [( | I LAx | × R REF / 15 ) –1], with I LAx in mA and R REF in k Ω , for all outputs except LA1 on LJ package.
4 E IMLA = 100 × max ( | I LAx – I LA(AV) | ) / I LA(AV) , where I LA(AV) is the average current of all active outputs.
