UNISONIC TECHNOLOGIES CO., A6043 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 Copyright © 2005 Unisonic Technologies Co., QW-R110-018,A FM STEREO MULTIPLEX DESCRIPTION The UTC A6043 is Phase Locked Loop(PLL) FM stereo multiplex IC. It is suitable for automotiv e applications and portable radio applications. 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 Package Packing A6043-G09-T A6043L-G09-T SIP-9 Tube
