DESCRIPTION
The TDA7407 is the newcomer of the CSP family
introduced by TDA7460/61. It uses the same in-
novative concepts and design technologies allo -
ing fully software programmability through IC
bus and overall cost optimisation for the system
designer.
The device includes a three band audioprocessor
with configurable inputs and absence of external

components for filter settings, a last generation
stereodecoder with multipath detector and a so-
phisticated stereoblend and noise cancellation
circuitry.
Strength points of the CSP approach are flexibility
and overall cost/room saving in the application,
combined with high performances.
