3 Description
The TAS5780M device is a high-performance, stereo
closed-loop Class-D amplifier with integrated audio
processor with 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.
