TPA6120A2 High Fidelity Headphone Amplifier Features 3 Description applications requiringa high-power output, very SNRof 128dB A-Weighted. high fidelity headphone amplifier, the TPA6120A2• THDof 112.5dB replacesa costly discrete design and allows music,• Current-Feedback Architecture not the amplifier, to be heard. The TPA6120A2's
current-feedback AB amplifier architecture delivers• Output Voltage Noiseof 0.9µVrmsat high bandwidth, extremely low noise, and up toGain= 1V/V (16Ω Load) 128dBof dynamic range.• Power Supply Range: ±5Vto ±15V
Three key features make current-feedback amplifiers• 1300V/µs Slew Rate outstanding for audio. The first featureis the high• Canbe configuredfor Single Endedor Differential slew rate that prevents odd order distortionInputs anomalies. The second featureis current-on-demand Independent Power Suppliesfor Low Crosstalk at the output that enables the amplifierto respond
