Description
The TDA7580 is an integrated circuit
implementing an advanced mixed analogue and
digital solution, to perform the signal processing
LQFP64
of an AM/FM channel. The HW & SW architecture
has been devised to perform a digital equalization
of the FM/AM channel, and a real rejection of
adjacent channels and any other signals,
interfering with the listening of the desired station.
In severe multiple path conditions, the reception is
improved to get high quality audio.
