TA7343AP

FM PLL MPX TOSHIBA Biplar Linear Integrated Circuit Silicon Monolithic TA7343AP TA7343AP The TA7343AP is PLL FM stereo multiplex IC. It is suitable for automotive applications and portable radio applications because of space merit by the package and wide supply voltage range. Features · Excellent stereo LED sensitivity : VL (ON) = 9mVrms (typ.) · Suitable for LED driving: ILED = 20mA (max.) · Recommendable input voltage range : Vin = 200~700mVrms · Operating supply voltage range: VCC = 3.5~12V · Excellent channel separation through entire audio frequency range: Sep = 45dB (typ.) Weight: 0.92g (typ.) · Low distortion: THD = 0.08% (typ.) at Vin = 200mVrms (stereo) · Built−in compulsive monaural function. (The VCO is stopped when the pin(7) is connected with the power supply line, and then the stereo indicator is turn off.) · Easy adjustment (the monitored free running frequency of VCO is 38kHz at pin(6). ) 1 2002-10-30 Block Diagram TA7343AP 2 2002-10-30 Maximum Ratings (Ta = 25°C) Characteristic Symbol Rating Unit Supply voltage LED voltage LED current Power dissipation Operating temperature Storage temperature VCC VLED ILED PD (Note) Topr Tstg 12 16 20 500 -30~75 -55~155 V V mA mW °C °C (Note) Derated above Ta = 25°C in the proportion of 4mW / °C Elecrical Characteristics 1.
