l'uscita cuffie è gestita da un TPA6120:
Description
The TPA6120A2 is a high fidelity audio amplifier built 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 the TPA6120A2 ensures that music, not the amplifier, is heard.
Features
80 mW into 600 From a ±12-V Supply at 0.00014% THD + N
Current-Feedback Architecture
Greater than 120 dB of Dynamic Range
SNR of 120 dB
Output Voltage Noise of 5 µVrms at Gain = 2 V/V
Power Supply Range: ±5 V to ±15 V
1300 V/µs Slew Rate
Differential Inputs
Independent Power Supplies for Low Crosstalk
Short Circuit and Thermal Protection
APPLICATIONS
Professional Audio Equipment
Mixing Boards
Headphone Distribution Amplifiers
Headphone Drivers
Microphone Preamplifiers
