FM STEREO MULTIPLEX
DESCRIPTION
LINEAR INTEGRATED CIRCUIT
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: V
CC
= 3V~12V
* High pilot lamp ON sensitivity: V
L(ON)
= 9mV
rms
(Typ.)
* Suitable for LED driving: I
LAMP
= 20mA (Max.)
* Recommendable input voltage range: V
IN
= 200~700mV
rms
* Low distortion: THD = 0.08% (Typ.) at V
IN
= 200mV
rms
(Stereo)
* VCO stop capability stereo lamp and turn off are simultaneously
operated by connect pin 7 to V
CC.
* Easy adjustment (The monitored free running frequency of VCO
is 38kHz at pin 6.)
