FM PLL MPX
TOSHIBA Biplar Linear Integrated Circuit Silicon Monolithic
TA7343AP
TA7343AP
The TA7343AP is PLL FM stereo multiplex IC. It is suitable for automotive applications and portable radio applications because of space merit by the package and wide supply
voltage range.
Features
· Excellent stereo LED sensitivity
: VL (ON) = 9mVrms (typ.)
· Suitable for LED driving: ILED = 20mA (max.)
· Recommendable input
voltage range
: Vin = 200~700mVrms
· Operating supply
voltage range: VCC = 3.5~12V
· Excellent channel separation through entire audio frequency range: Sep = 45dB (typ.)
Weight: 0.92g (typ.)
· Low distortion: THD = 0.08% (typ.) at Vin = 200mVrms (stereo)
· Built−in compulsive monaural function. (The VCO is stopped when the pin(7) is connected with the power supply line, and then the stereo indicator is turn off.)
· Easy adjustment (the monitored free running frequency of VCO is 38kHz at pin(6). )
