| UNISONIC TECHNOLOGIES CO., A6043 FM STEREO MULTIPLEX DESCRIPTION The UTC A6043 is Phase Locked Loop(PLL) FM stereo multiplex IC. It is suitable for automotive applications and portable radio applications. LINEAR INTEGRATED CIRCUIT FEATURES * Low and wide operation: VCC= 3V~12V * High pilot lamp ON sensitivity: VL(ON) = 9mVrms (Typ.) * Suitable for LED driving: ILAMP = 20mA (Max.) * Recommendable input voltage range: VIN = 200~700mVrms * Low distortion: THD = 0.08% (Typ.) at VIN = 200mVrms(Stereo) * VCO stop capability stereo lamp and turn off are simultaneously operated by connect pin 7 to VCC. * Easy adjustment (The monitored free running frequency of VCO is 38kHz at pin 6.) SIP-9 *Pb-free plating product number: A6043L ORDERING INFORMATION Order Number Normal Lead free A6043-G09-T A6043L-G09-T Package SIP-9 Packing Tube www.unisonic.com.tw Copyright (c) 2005 Unisonic Technologies Co., 1 QW-R110-018,A A6043 BLOCK DIAGRAM L.P.F-1 2 INPUT 1 AF PHASE DETECTOR DC 19kHz<90 PILOT DETECTOR STEREO DECODER 8 LEFT 9 RIGHT 7 L.P.F-2 Vco 4 LINEAR INTEGRATED CIRCUIT VCO 76kHz 1/2 1/2 TRIGGER 19kHz<0 38kHz 6 STEREO SWITCH 1/2 STABILZED POWER SUPPLY 5 GND 3 VCC ST.LAMP UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 QW-R110-018,A A6043 ABSOLUTE MAXIMUM RATINGS (Ta = 25 ) PARAMETER Supply Voltage Lamp Voltage Lamp Current Power Dissipation Operating Temperature Storage Temperature LINEAR INTEGRATED CIRCUIT SYMBOL VCC VLAMP ILAMP PD TOPR TSTG RATINGS 12 16 20 500 0 ~ +70 -40 ~ +150 UNIT V V mA mW ELECTRICAL CHARACTERISTICS 1.
