www.vishay.com Vishay Semiconductors The value of R5 depends upon the IL300 Transfer Gain (K3). K3 is targeted to be a unit gain device, however to minimize + R1 ISO the part to part Transfer Gain variation, Infineon offers K3 To control Voltage input AMP monitor graded into ± 5 % bins. R5 can determined using the +1 following equation, - R2 VOUT R3 x R1 + R2   R5 = -------------- x --------------------- V R2 x K3 MONITOR  iil300_16 Fig. 11 - Isolated Control Amplifier or if a unity gain amplifier is being designed For best input offset compensation at U1, R2 will equal R3. (VMONITOR = VOUT, R1 = 0), the equation simplifies to: The value of R1 can easily be calculated from the following.
