TPA6120A2DWPG4 (TEXAS INSTRUMENTS)

The TPA6120A2DWPG4 is a High Fidelity Stereo Headphone Amplifier for applications requiring a high-power output. 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.
