FOUR BANDS DIGITAL CONTROLLED GRAPHIC EQUALIZER

STMicroelectronics 

Figure 2: Application Circuit

TDA7316

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. In fact the dedicated ADDR

pin allows 2 addresses selection. Anyway, the ad-

dress of the graphic equalizer is different from the

audioprocessor one.

For example, 9 bands are implemented by using

of 2 TDA7316 plus an audioprocessor (TDA731X

family).

In case one filtering cell is not needed, a short cir-

cuit must be provided between the P1xy and

P2xy pins.
