Description
The TA2145AFG is a 3V Stereo Headphone Amplifier developed for playback stereo headphone equipment (3V USE). It is built with dual preamplifiers, dual OCL power amplifiers, motor governor, DC volume control, and a preamplifier on/off switch.
Specifications and Features
- Built-in preamplifier
- Input coupling condenser-less
- Built-in input capacitor for reducing buzz noise
- Low noise: Vni = 1.2 µVrms (typ.)
- Preamplifier on/off switch
- Built-in power amplifier - OCL (Output condenser-less)
- Voltage gain: GV = 31 dB (typ.)
- Built-in motor governor (Current proportion type)
- Built-in DC volume control function - ATT = 82dB (Ta = 25°C, typ.)
- Built-in bass boost function
- Low supply current (VCC = 3V, f = 1kHz, PRE OUT = 100 mVrms, Ta = 25°C, typ.)
- Quiescent supply current - PRE + PW: ICCQ = 8.5 mA, GVN: ICC = 2.5 mA
- 0.1mW × 2 ch output - ICC1 = 9.8 mA (RL = 32 Ω), ICC2 = 10.5 mA (RL = 16 Ω)
- 0.5mW × 2 ch output - ICC3 = 14.0 mA (RL = 32 Ω), ICC4 = 16.5 mA (RL = 16 Ω)
- Operating supply voltage range (Ta = 25°C) - VCC (opr) = 1.8~3.6V, GVN VCC (opr) = 2.1~3.6V (Motor voltage = 1.8V)
Application Scenarios
The TA2145AFG can be used in various stereo headphone equipment that requires a 3V amplifier. It is suitable for applications where low noise, bass boost, and precise volume control are desired.
Comparison
Advantages- Built-in preamplifier and power amplifier for enhanced audio performance.
- Low noise design for high-quality sound reproduction.
- Built-in bass boost function for enhanced bass response.
- Wide operating supply voltage range for flexibility in different applications.
Disadvantages- Requires a 3V power supply, limiting compatibility with devices using higher voltage levels.
