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.

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...
