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.
