TDA1593T中文资料飞利浦数据手册PDF规格书

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.

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.
