TDA1596T

INTEGRATED CIRCUITS DATA SHEET TDA1596T IF amplifier/demodulator for FM radio receivers Product specification File under Integrated Circuits, IC01 April 1991 Philips Semiconductors Product specification IF amplifier/demodulator for FM radio receivers GENERAL DESCRIPTION TDA1596T 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.
