voltage is set up low relativity, for NEW FCC.
TA2111N
Features
· · · · · · · For NEW FCC. AM Detector coil, FM IFT, IF coupling condenser are not needed. For adopting ceramic discriminator, it is not necessary to adjust the FM quad detector circuit. Built-in FM MPX VCO circuit. Built-in varactor diode for AFC. Built-in AM low cut circuit. Low supply current. (VCC = 3 V, Ta = 25°C) ICCq (FM) = 9.0 mA (typ.) ICCq (AM) = 5.0 mA (typ.) · Operating supply
voltage range: VCC = 1.8~7 V (Ta = 25°C)
