The TAS5754M device is a high-performance, stereo closed-loop amplifier with integrated audio processor with PurePath™ HybridFlow architecture. To convert from digital to analog, it uses a high performance DAC with Burr-Brown mixed signal heritage. It requires only two power supplies: one DVDD for low-voltage circuitry and one PVDD for high-voltage circuitry. It is controlled via a software control port using standard I²C communication. In the family, the TAS5756M uses traditional BD modulation, ensuring low distortion characteristics. The TAS5754M uses 1SPW modulation, reducing the idle current draw at the expense of slightly higher distortion.

The unique HybridFlow architecture allows the system designer to choose from several configurable DSP programs, specifically designed for use in popular audio end equipment like Bluetooth (BT) Speakers, Sound Bars, Docking Stations, Subwoofers. This combines the flexibility of a fully programmable device with the fast download time and ease of use of a fixed function ROM device.

An optimal mix of thermal performance and device cost is provided in the 90 mΩ rDS(ON) of the output MOSFETs. Additionally, a thermally enhanced 48-Terminal TSSOP provides excellent operation in the elevated ambient temperatures found in modern consumer electronic devices.
