For best input offset compensation at U1, R2 will equal R3.
The value of R1 can easily be calculated from the following.
The value of R5 depends upon the IL300 Transfer Gain (K3).
K3 is targeted to be a unit gain device, however to minimize
the part to part Transfer Gain variation, Infineon offers K3
graded into ± 5 % bins. R5 can determined using the
following equation,
or if a unity gain amplifier is being designed
(VMONITOR
= VOUT, R1 = 0), the equation simplifies to:
