TA7331F

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA7331P,TA7331F TA7331P / F Low Quiescent Current Audio Power Amplifier For Mini / Micro Cassette Tape Recorder The TA7331P and TA7331F are an audio power amplifier designed for use in low voltage consumer applications. Especially it is suitable for mini / micro cassette tape recorder and pocket radio appliocations. As the quiescent current is only 3mA at 3V, it is best for battery operation. Features · Operating supply voltage range : VCC (opr) = 2~5V... TA7331P (Ta = 25°C) VCC (opr) = 2~4V... TA7331F (Ta = 25°C) · Low quiescent current: ICCQ = 3mA (typ.) (VCC = 3V, Ta = 25°C) · TA7331F (SO) is standard model of flat package Weight SIP9−P−2.54A: 0.92g (typ.) SSOP16−P−225−1.00: 0.14g (typ.)
