IF amplifier/demodulator for FM radio
receivers
Product specification
TDA1596T
GENERAL DESCRIPTION
The TDA1596T provides IF amplification, symmetrical quadrature demodulation and level detection for quality home and
car FM radio receivers and is suitable for both mono and stereo reception. It may also be applied to common front-ends,
stereo decoders and AM receiver circuits.
Features
• Simulates behaviour of a ratio detector (internal field strength and detuning-dependent voltage for dynamic AF signal
muting)
• Mono/stereo blend and field strength indication control voltage
• Three-state mode switch for FM, mute-on / FM, mute-off / FM-off
• Internal compensation of AF signal total harmonic distortion (THD)
• Two open collector stop pulse outputs for microcomputer tuning control (can be one stop pulse output by
wired-ANDing)
• Internal reference voltage source
• Built-in hum and ripple rejection circuits.
