AN249

The CS5333 and CS5340 are both available in a 16-pin TSSOP package. As can be seen from Table 2,

all but three pins correlate directly in terms of functionality. These three pins account for a difference in

operational mode selection and a separate voltage supply pin for the CS5340 digital core.
