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.
