TA8186P

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8186P AM / FM IF + MPX TA8186P is the AM / FM IF + MPX system IC, which is designed for radio cassette recorders and music centers. Features · Compact package (DIP16), and small number of external parts. · AM IFT is also used for VCO resonator. · Built−in FM soft muting circuit. · Operating supply voltage range: VCC (opr) = 3.5~13V (Ta = 25°C) At FM soft mute using: VCC (opr) = 3.5~9V (Ta = 25°C) Weight: 1.00g (typ.) ※Handle with care to prevent devices from deteriorations by static electricity.
