Description

The TAS2555 device is an amplifier with integrated boost converter and programmable digital signal
processor. It can operate in various modes supporting Class-D, Class-G, and Class-H. The on-chip
voltage and current sense, together with TI’s SmartAmp

®

algorithm, protect the speaker against

overheating and excessive excursion.

The TAS2555EVM supports evaluation and development with the TAS2555 device through the following
interfaces:

•

USB interface

–

TAS2555 control through Purepath™ Console 3 (PPC3) GUI, USB-HID

–

USB-class audio device, compatible with Microsoft

®

Windows

®

7+

•

Digital audio AP and PSIA interface through 100-mil headers

•

TI Learning Board 2 for speaker characterization

•

SPI interface for TAS2555 control

•

I
