Low Current Consumption Headphone Amplifier (Built-in input selector)
TA2170FTG
The TA2170FTG is a stereo headphone amplifier built in the
selector switch of 3 inputs.
The mute switch is built in each 3 input, and an output can
choose 1 output or a mixer 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 inputs mode)
Weight: 0.03 g (typ.)
Marking: 2170
ICCQ = 1.1 mA (3 inputs mode)
• 0.1 mW × 2 ch
ICC = 2.2 mA (1 input mode)
ICC = 2.3 mA (2 inputs mode)
ICC = 2.4 mA (3 inputs mode)
• 0.5 mW × 2 ch
ICC = 4.1 mA (1 input mode)
ICC = 4.2 mA (2 inputs mode)
ICC = 4.3 mA (3 inputs mode)
• GV = −0.3dB (1 input mode, typ.)
• Built-in signal level adjustment circuit, so that a 1 output or a mixer output doesn’t change a feeling of volume
either.
• 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
