TA7358AP

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA7358AP FM Front−End TA7358AP The TA7358AP is designed for a FM front−end application,which is suitable to a portable radio or a radio cassette. Comparing with conventional types, supply voltage dependence, overload characteristics and spurious radiation characteristics are improved. Features · Wide supply voltage range : VCC = 1.6~6.0V · Excellent supply voltage dependence of local oscillator : Oscillation stop VCC = 0.9V (typ.) · Improved inter−modulation characteristics by double balanced type mixer circuit. · Low spurious radiation. · Built−in clampping diode for the local oscillator output.
