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. (VCC = 1.2V, Ta = 25°C) PB mode . ................... ICCQ2 = 2.6m A (typ.) Radio mode ............. ICCQ3 = 2.4m A (typ.) Radio- REC mode ... - Low power dissipation. PB mode : 2.9m W (typ.) MIC- REC mode : 8.9m W (typ.) - Operating supply voltage range. (Ta = 25°C) VCC (opr) = 0.9~4V VCC (opr) (REC) = 1.8~4V ICCQ4 = 3.0m A (typ.) MIC- REC mode ... ..... ICCQ5 = 4.5m A (typ.)
