9. Application Information
9.1. Application circuit
The exact drive circuit for the LEDs, the shunt resistor, photodiodes and power supply filter components can
change for each application. The table below summarizes a possible set of external components.
A typical application diagram is shown in Figure 23. Note that the capacitor on Cext has a defined range of
10..100nF, however 68nF is highly recommended to give the best results.
