Description
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.

Test Condition
― Vin = 0, ALC ON ――
― THD = 1%
―
Vout = 0.3 Vrms BW = 400 Hz~30 kHz
― Vin = 0.0178 Vrms (−35dBV) ― 3dB up
―
Vin = 1.41 mVrms (−57.0dBV) → 0.014 Vrms (−37.0dBV)
―
Vin = 0.014 Vrms (−37.0dBV) → 0.447 mVrms ...
