3 Description
The TAS5782M device is a high-performance, stereo
closed-loop Class-D amplifier with integrated audio
processor with up to 96-kHz architecture. To convert
from digital to analog, the device uses a high
performance DAC with Burr Brown™ audio
technology. It requires only two power supplies: one
DVDD for low-voltage circuitry and one PVDD for
high-voltage circuitry. It is controlled by a software
control port using standard I²C communication.
An optimal mix of thermal performance and device
cost is provided in the 90 mΩ r_DS(on) of the output
MOSFETs. Additionally, a thermally enhanced 48-Pin
TSSOP provides excellent operation in the elevated
ambient temperatures found in modern consumer
electronic devices.
