TA2132BP
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 varactor diode for AFC Low supply current: (VCC = 3 V, Ta = 25°C) ICCq (FM) = 7.3 mA (typ.) ICCq (AM) = 3.6 mA (typ.) · Operating supply voltage range: VCC = 1.8~7 V (Ta = 25°C) Note: The IC may be destroyed due to incorrect orientation of device’s mounting. Weight DIP16-P-300-2.54A : 1.00 g (typ.) SSOP16-P-225-1.00A : 0.14 g (typ.)
