Low Current Consumption Headphone Amplifier (Built-in Input Selector)
The TA2170FLG is a stereo headphone amplifier built-in
selector switch for three inputs.
The mute switch is built into each of the three inputs, and a
single or mixer output can be selected for the output.
Features
• Low current consumption
VCC = 3 V, f = 1 kHz, RL = 32 Ω, typ.
• No signal mode
ICCQ = 0.9 mA (1-input mode)
ICCQ = 1.0 mA (2-input mode)
Weight: 0.05 g (typ.)
Marking: 2170G
ICCQ = 1.1 mA (3-input mode)
• 0.1 mW × 2 ch
ICC = 2.2 mA (1-input mode)
ICC = 2.3 mA (2-input mode)
ICC = 2.4 mA (3-input mode)
• 0.5 mW × 2 ch
ICC = 4.1 mA (1-input mode)
ICC = 4.2 mA (2-input mode)
ICC = 4.3 mA (3-input mode)
• GV = −0.3 dB (1-input mode, typ.)
• Built-in signal level adjustment circuit to eliminate any perceptible change in volume whether single or mixer
output is used.
• Built-in power switch
• Built-in all mute switch
• Built-in mute switch at each buffer amplifier
• Built-in one side mute switch at buffer amplifier 1
• Operating supply voltage range (Ta = 25°C): VCC1 (opr) = 1.8 to 4.5 V
VCC2 (opr) = 0.9 to 4.5 V
