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