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.
Key Features
- Balanced limiting amplifier.
- Balanced coincidence demodulator.
- Two open-collector stop pulse outputs for microcomputer tuning control.
- Simulated behaviour of ratio detector (internal field strength and detuning dependent voltage for dynamic AF signal muting).
- Mono/stereo blend field strength indication control voltage.
- AFC output.
- 3-state mode switch for FM-MUTE-ON, FM-MUTE-OFF and FM-OFF.
- Internal compensation of AF signal.
