Summary in PDF File


Ordering number EN1140D Monolithic Linear IC LA1143 FM IF System for Car Radios Overview The LA1143 is an IF system IC designed for FM car stereo receivers It features versatile muting characteristics and allows receiver designers to realize the muting performance according to their design concept Since the muting characteristics can be varied with a switch or a semi fixed resistor DX Local switching will be accomplished with ease Package Dimensions unit mm 3006B DIP16 LA1143 Functions IF amplification limiter AF preamplifier Signal meter output Muting at detuning Quadrature detector AFC output AGC output Muting at small input SANYO DIP16 Features 1 Versatile mutings a When muting operation is performed under a weak signal strength an attenuation slope of the audio output against the input signal strength variations can be set at any given value b Maximum muting attenuation can be selected to be approximately 6 to 40dB c Input signal strength level which actuates the muting circuit can be set freely 2 High limiting sensitivity 25 dB typ with muting off provides a good quieting characteristic 3 High S N 78dB typ 4 Low distortion 0 05 typ available if used with double tuned circuits 5 Go
