Product specification
IF amplifier/demodulator for FM radio
receivers
TDA1599
FEATURES
Balanced limiting amplifier
Balanced coincidence demodulator
Two open-collector stop pulse outputs for
microcomputer tuning control
Simulated behaviour of a 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 total harmonic
distortion (THD)
Built-in hum and ripple rejection circuits.
GENERAL DESCRIPTION
The TDA1599 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 receiver circuits.
