1.5V Stereo Headphone Amplifier
TA2123AF TOSHIBA Bipolar Integrated Circuit Silicon Monolithic
TA2123AF 1.5V Stereo Headphone Amplifier
The TA2123AF is the system amplifier IC which is developed
for playback stereo headphone equipments. It is built in dual
auto−reverse preamplifiers, dual power amplifiers with bass /
treble boost function, AMS (automatic music sensor) function,
beep function, AGC for power amplifier etc.
Features Power amplifier stage In case of output coupling type, the supply current
decreases.
(built−in center amplifier switch) Built−in bass boost function Built−in treble boost function Built−in power amplifier muting function Built−in input terminal for beep signal Built−in input capacitor for reducing buzz noise GV = 24dB (typ.) Built−in AGC circuit (in case of boost mode, this circuit operates.) Low supply current
(VCC = 1.3V, f = 1kHz, RL = 32Ω, Ta = 25°C, typ.) Preamplifier stage Auto�reverse compatible Built�in input capacitor for reducing buzz noise Input coupling condensor�less Built�in metal mode drivers Preamplifier muting function Built�in ripple filter circuit Built�in AMS (automatic music sensor) function (mixer amplifier and level comparator) Built�in power switch Operating supply voltage range (Ta = 25°C)
VCC (opr) = 0.95~2.2V
Weight: 0.17g (typ.)
