TAS5755M Digital Input Audio Amplifier

Texas Instruments TAS5755M Digital Input Audio Amplifier is a single-chip flexible digital audio solution with integrated processing. This integrated processing supports 2.1 (2 speakers + subwoofer), 2.0 or stereo (2 speakers), and mono (high power speaker) modes. Its high efficiency, low 80mΩ R_DSON, and pad-up package allows the device to output up to 2×50W or 1×100W. TAS5755M leverages two full H-bridges used for each channel in stereo mode. In 2.1 mode, TAS5755M runs two independent speaker channels using two half-bridges while using a full bridge to drive a subwoofer. Finally, in mono mode, TAS5755M supports pre-filter parallel bridge-tied load (PBTL) using only one filter stage to reduce total system size and cost.
