The TDA7541 is a high performance tuner circuit  
with stereo decoder for AM/FM car radio. It  
contains a mixer, IF amplifier, demodulator for AM  
and FM, stereo decoder, quality detection, ISS  
filter and PLL synthesizer with IF counter on a  
single chip. Use of BICMOS technology allows the  
implementation of several tuning functions and a  
minimum of external components.  
■ Additional features  
– VCO for world tuning range
