The TAS5756M device is a high-performance, stereo closed-loop amplifier withintegrated audio processor with PurePath HybridFlow architecture. To convertfrom digital to analog, it uses a high performance DAC with Burr-Brown mixedsignal heritage. It requires only two power supplies: one DVDD for low-voltagecircuitry and one PVDD for high-voltage circuitry. It is controlled via asoftware control port using standard I2C communication. In thefamily, the TAS5756M uses traditional BD modulation, ensuring low distortioncharacteristics. The TAS5754M uses 1SPW modulation, reducing the idle currentdraw at the expense of slightly higher distortion.
The unique HybridFlow architecture allows the system designer to choose fromseveral configurable DSP programs, specifically designed for use in popularaudio end equipment such as bluetooth (BT) speakers, sound bars, dockingstations, and subwoofers. This combines the flexibility of a fully programmabledevice with the fast download time and ease of use of a fixed function ROMdevice.
An optimal mix of thermal performance and device cost is provided in the 90mΩ rDS(on) of the output MOSFETs. Additionally, a thermally enhanced48-Pin HTSSOP provides excellent operation in the elevated ambient temperaturesfound in modern consumer electronic devices.
