TA7358APG TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA7358APG FM Front-End The TA7358APG 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.) Weight: 0.92g (typ.) * Improved inter-modulation characteristics by double balanced type mixer circuit. * Low spurious radiation. * Built-in clampping diode for the local oscillator output.
