Low Current Consumption Headphone Amplifier (for 1.5-V/3-V Use)
TA2152FLG
The TA2152FLG 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
Weight: 0.05 g (typ.)
Marking: 2152
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
