GENERAL DESCRIPTION
The TDA1597 provides IF amplification, symmetrical
quadrature demodulation and level detection for quality
home and car FM radio receivers and is suitable for mono
and stereo reception. It may also be applied to common
front-ends, stereo decoders and AM receivers circuits.
All pin numbers mentioned in this data sheet refer to the
SO version (TDA1597T) unless otherwise specified.
