TA2152FL Low Current Consumption Headphone Amplifier (for 1.5-V/3-V Use)
The TA2152FL is a headphone amplifier of low current
consumption type developed for portable digital audio.
It is especially suitable for portable CD players, portable MD
players etc.
Features Low current consumption The power amplifier output stage can be driven using a
single battery.
As a result, overall current consumption is low. Built-in center amplifier switch
For the output-coupling type, the consumption current has
been decreased still further. Current value (VCC1 = 2.4 V, VCC2 = 1.2 V , f = 1 kHz, RL = 16 Ω, Ta = 25°C, typ.) Output-coupling type No Signal: ICC (VCC1) = 0.4 mA, ICC (VCC2) = 0.3 mA 0.1 mW × 2 ch: ICC (VCC1) = 0.5 mA, ICC (VCC2) = 2.2 mA 0.5 mW × 2 ch: ICC (VCC1) = 0.5 mA, ICC (VCC2) = 5.0 mA OCL type No Signal: ICC (VCC1) = 0.7 mA, ICC (VCC2) = 0.7 mA 0.1 mW × 2 ch: ICC (VCC1) = 0.7 mA, ICC (VCC2) = 4.5 mA 0.5 mW × 2 ch: ICC (VCC1) = 0.8 mA, ICC (VCC2) = 10.0 mA Output power: Po = 8 mW (typ.)
(VCC1 = 2.4 V , VCC2 = 1.2 V, f = 1 kHz, RL = 16 Ω, THD = 10%, Ta = 25°C) Voltage gain: GV = 11.5dB (typ.) Built-in beep function Built-in low-pass compensation (output-coupling type) Built-in mute switch Built-in power switch Operating supply voltage range (Ta = 25°C)
VCC1 (opr) = 1.8 V~4.5 V
VCC2 (opr) = 0.9 V~4.5 V
Weight: 0.05 g (typ.)
Marking: 2152
