TDA7316 Datasheet, PDF (5/10 Pages) STMicroelectronics – FOUR BANDSDIGITAL CONTROLLED GRAPHIC EQUALIZER

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.
