APPLICATIONS INFORMATION  
RECOMMENDED EXTERNAL COMPONENTS  
Figure 64 External Component Diagram  
1. When operating LOUT2 and ROUT2 in class D mode, it is recommended that LC filtering is placed as close to  
the LOUT2 and ROUT2 pins as possible. Low ESR components should be used for maximum efficiency. It is  
recommended that a filter, consisting of a 33µH inductor and a 220nF capacitor, is used for optimal performance.  
2. The addition of ferrite beads to the outputs of LOUT2 and ROUT2 will suppress any potential interference noise  
produced by the class D switching clocks.
