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.)
SIP-9
*Pb-free plating product number: A6043L
