TDA1597 Overview
TDA1597 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 mon 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.
