TA2011S

Mic Amp IC TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2011S The TA2011S is suitable for audio mic amplifier of portable cassette tape recorder and karaoke. Features · Built in ALC DET Circuit. · Built in NFB resistance. (Voltage gain is fixed): Gv = 47dB (typ.) f = 1 kHz, ALC OFF · ALC Level: Vout (ALC) = 0.6 Vrms (typ.) · ALC Range: RALC = 58dB (typ.) Weight: 0.7 g (typ.) · Operating Supply Voltage Range: VCC (opr) = 4~14 V (Ta = 25°C) · When the ALC circuit is off, pin 6 must be connected directly to ground.
