TA8155F

TA8155F / FN TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8155F,TA8155FN REC / PB System Dual Pre−amplifier (1.5 / 3V USE) The TA8155F and TA8155FN are REC / PB system dual pre amplifier ICs, which are developed for low voltage operation (1.5 / 3V use). These are especially suitable for a stereo headphone cassette player. Features · Built−in dual playback amplifiers. Input coupling condenser−less. Built−in capacitor for buzz noise. · Built−in dual buffer amplifiers. For radio signal inut. Monitor for REC mode. · B Built−in dual microphone amplifiers. uilt−in an ALC circuit for MIC−REC mode. Attack time. : 0.1s (typ.) Recovery time. : 3.5s (typ.) · · · Built−in dual recording amplifiers. Single−end output type. Built−in a power switch. Low quiescent current.
