Product specification
IF amplifier/demodulator for
FM car radio receivers
TDA1593
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
• Internal compensation of AF signal total harmonic
distortion (THD)
• Built-in hum and ripple rejection circuits.
GENERAL DESCRIPTION
The TDA1593 provides IF amplification, symmetrical
quadrature demodulation and level detection for quality
FM car 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 (TDA1593T) unless otherwise specified.
