Description
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.
