3 Detail:
In applications requiring a high-power output, very high fidelity headphone amplifier,the TPA6120A2
replaces a costlydiscrete design and allows music,not the amplifier, to be heard. The TPA6120A2's
current-feedback AB amplifier architecture delivers high bandwidth, extremely low noise, and up to
128dB of dynamic range.
Three key features make current-feedback amplifiers outstanding for audio. The first feature is the high slew rate that prevents odd order distortion anomalies. The second feature is current-on-demand
at the output that enables the amplifier to respond quickly and linearly when necessary without risk of
output distortion. When large amounts of output power are suddenly needed, the amplifier can
respond extremely quickly without raising the noise floor of the system and degrading the signal-to-noise ratio. The third feature is the gain-independent frequency response that allows the full bandwidth of the amplifier to be used over a wide range of gain settings.
