TOSHIBA Bipolar Integrated Circuit Silicon Monolithic
TA2123AFG
1.5V Stereo Headphone Amplifier
The TA2123AFG is the system amplifier IC which is developed
for playback stereo headphone equipments. It is built in dual
autoreverse 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.
