TPA6120A2
SLOS431 – MARCH 2004
HIGH FIDELITY HEADPHONE AMPLIFIER
80 mW into 600
From a ±12-V Supply at
The TPA6120A2 is a high fidelity audio amplifier built
0.00014% THD + N
on
a
current-feedback
architecture.
This
high
bandwidth, extremely low noise device is ideal for

high performance equipment. The better than 120 dB

of dynamic range exceeds the capabilities of the

human ear, ensuring that nothing audible is lost due
to the amplifier. The solid design and performance of
Output Voltage Noise of 5 Vrms at
the TPA6120A2 ensures that music, not the amplifier,
Gain = 2 V/V
is heard.
Power Supply Range:
±5 V to ±15 V
Three key features make current-feedback amplifiers
