TA2145AF
3 V Stereo Headphone Amplifier (3 V USE)
The TA2145AF is developed for play-back stereo headphone
equipments (3 V USE).
It is built in dual preamplifiers, dual OCL power amplifiers,
motor governor, DC volume control and preamplifier on/off switch
etc.
Features
Built-in preamplifier
Input coupling condenser-less
Built-in input capacitor for reducing buzz noise
Low noise: Vni = 1.2 Vrms (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 = 3 V, f = 1 kHz, PRE OUT = 100 mVrms, Ta = 25°C, typ.)
Quiescent supply current
PRE + PW: ICCQ = 8.5 mA
GVN: ICC = 2.5 mA
0.1 mW × 2 ch output
ICC1 = 9.8 mA (RL = 32 )
ICC2 = 10.5 mA (RL = 16 )
0.5 mW × 2 ch output
ICC3 = 14.0 mA (RL = 32 )
ICC4 = 16.5 mA (RL = 16 )
Operating supply voltage range (Ta = 25°C)
VCC (opr) = 1.8~3.6 V
GVN VCC (opr) = 2.1~3.6 V (Motor voltage = 1.8 V)
