TAS5755MDFD, Audio Amplifiers 50-W stereo, 100-W mono, 8- to 26.4-V, digital input open loop Class-D audio amplifier w/ 2.1 mode 56-HTSSOP 0

Semiconductors\Audio ICs\Audio AmplifiersTAS5755M Digital Input Audio AmplifierTexas 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 2x50W or 1x100W. 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.
