UNISONIC TECHNOLOGIES CO., A6043 LINEAR INTEGRATED CIRCUIT 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. 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.)
