TA2123AF Overview
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.
TA2123AF Key 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.)
