TEST AND APPLICATION INFORMATION
Figures 13 to 15 indicate typical systems environment of the TDA1315H. They are intended to give examples of which
external blocks may be added to compose a system for particular requirements. The loop filter configuration and values
in the examples meet the requirements for mid-end and high-end audio applications.
