TDA7502
Application Scheme
The The TDA7502 IC will interface with an exter-
nal CODEC chip (i.e. the TDA7531). The CODEC
chip contains A/D converters that convert the
audio data and send it to the TDA7502 IC for sig-
nal processing. The TDA7502 then sends the
processed audio data back to the CODEC for D/A
conversion. A block diagram of the system is
shown in Fig. 1 below.
