TA7330F

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA7330P,TA7330F TA7330P / F Preamplifier With ALC Circuit For Mini / Micro Cassette Tape Recorder The TA7330P and TA7330F are preamplifier for 3V or 4.5V battery use. It consists of low noise preamplifier and ALC (automatic level control) circuit, and is suitable for mini / micro cassette tape recorder applications. Features · Low supply voltage use: VCC (opr) = 2~5V (Ta = 25°C) · Low noise : Vni = 1µVrms (typ.) · Wide ALC range : WALC = 40dB (typ. · Low quiescent current : ICCQ = 0.75mA (typ.) (VCC = 3V, Ta = 25°C) · TA7330F (SO) is standard model of flat package. Test Circuit / Block Diagram TA7330P + + VCC=3V Weight SIP7−P−2.54A: 0.72g (typ.)
