Figure 2: Application Circuit
The five bands graphic equalizer is used in con-
junction with a TDA7318 (or another audioproces-
sor of the SGS-THOMSON 731X family).
The audioprocessor bass and treble tone can fur-
nish two extra filter bands.
Application requiring higher number of external
equalizer bands could be implemented by cas-
cading 2 or more TDA7317 devices. In fact the
dedicated ADDR pin allows 2 addresses selec-
tion. Anyway, the address of the graphic equalizer
is different from the audioprocessor one.
For example 11 bands are implemented by use of
2 TDA7317 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.
