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

Weight: 0.17g (typ.)

· 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

· G = 24dB (typ.)

· Built−in AGC circuit (in case of boost mode, this circuit operates.)
