TA2152FNG
Low Current Consumption Headphone Amplifier (for 1.5-V/3-V Use)
TA2152FNG
The TA2152FNG 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 drive stage can be driven using a single battery.
As a result, overall current consumption is low.
⢠Built-in center amplifier switch
Weight: 0.14 g (typ.)
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 â¦, Ta = 25°C, typ.)
⢠Output-coupling type
⢠No Signal: ICC (VCC1) = 0.4 mA, ICC (VCC2) = 0.3 mA
⢠0.1 mW à 2 ch: ICC (VCC1) = 0.5 mA, ICC (VCC2) = 2.2 mA
⢠0.5 mW à 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 à 2 ch: ICC (VCC1) = 0.7 mA, ICC (VCC2) = 4.5 mA
⢠0.5 mW à 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 â¦, THD = 10%, Ta = 25°C)
⢠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
