Other Parts Discussed in Thread: TAS5721

Hi all

Would  you mind if we ask TAS5721?

This device has HP amplifier internally.
What is the main benefit?
Is it Direct Path? or something else?

Kind regards,

Hirotaka Matsumoto

    Hi, Matsumoto-san, 

    Effectively, the TAS5721 has an integrated Line/Headphone DirectPath Driver. This driver is capable if delivering 2-Vrms Stereo using a single power supply, without the need of DC-blocking capacitors. You can find more information about the integrated Driver in Page 61 of the datasheet.

    Hi, Matsumoto-san, 

    In some subsystems a headphone output option is required to stream a different audio content from the main speaker outputs. Of course having an available driver integrated in the amplifier saves the BOM count of one HP/line driver :).
