IB1 = bias current of A1 (5pA, typ) IB2 = bias current of A2 (5pA, typ) N = log conformity error (0.01%, 0.06%, typ) 0.01% for n = 5, 0.06% for n = 7.5 VOSO = output offset voltage (3mV, typ) m = number of decades over which N is specified: Example: what is the error when I1 = 1µA and I2 = 100nA VmV OUT =± ( ) − − ± ( )( ) ± −− −− 0 5 0 0015 10 5 10 10 5 10 2 0 0001 5 3 0 612 712 . . log • • .. = 0.5055V Since the ideal output is 0.5V, the error as a percent of reading is % . . %. % error =• = 0 5055 05 100 1 1 For the case of voltage inputs, the actual transfer function is VV K V R I E R V R I E R Nm V OUT B OS B OS OSO = ( ) ± ( ) ± ± ±± 05 1 1 1 1 1 1 2 2 2 2 2 .log – – ∆ Where E R and E R OS OS 1 1 2 2 are considered to be zero for large values of resistance from external input current sources. |
