... Figure 2: Application Circuit A five bands graphic equalizer is implemented us- ing the 4 bands of the TDA7316 plus a fifth band obtained from the bass control circuit of the TDA7318 (or another audioprocessor of the SGS- THOMSON 731X family). Applications requiring higher number of external equalizer bands could be implemented by cascading 2 or more TDA7316 devices ...

... TDA7316 BUS INTERFACE Data transmission from microprocessor to the TDA7316 and viceversa takes place thru the 2 2 wires I C BUS interface, consisting of the two lines SDA and SCL (pull-up resistors to positive supply voltage must be externally connected). Data Validity As shown in fig. 3, the data on the SDA line must be stable during the high period of the clock ...
