SA1140 FM RADIO IC FOR DIGITAL TUNING SYSTEM DESCRIPTION The SA1140 is an IF system IC designed for FM car stereo receivers. It features versatile muting characteristics which can be varied with external parts. FEATURES www.DataSheet4U.com * Muting characteristics a) Muting operation is performed under weak signal strength. b) Maximum muting attenuation can be selected to be approximately 6 to 40 dB. c) Input signal strength level which actuates the muting circuit can be set freely. * High limiting sensitivity * High S/N (78 dB typ.) * Good AMR * Signal meter drive output proportional to the input signal strength in dB (suitable to control multiplex IC SA3370).
