Description

The TDA7580 is an integrated circuit implementing an advanced mixed analogue and digital solution, to perform the signal processing 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.
