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.
