LA1140

Ordering number: EN 729E Monalithic Linear IC LA1140 FM IF System for Car Radio Overview The LA1140 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 3020A-SIP16 [LA1140] Functions . IF amplification/limiter . Quadrature detector . AF preamplifier . AFC output . Signal meter output . AGC output . Muting bandwidth . Muting under weak signal strength SANYO : SIP16 Features . Versatile muting 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 40 dB. c) Input signal stre...
