Description
The TAS2557 device is an amplifier with integrated boost converter and programmable digital signalprocessor. The output amplifier is a Class-D device that can be driven to higher output levels with the onchipClass-H boost. The on-chip voltage and current sense, together with TI’s Smart Amp algorithm,protect the speaker against overheating and excessive excursion.The TAS2557 EVM supports evaluation and development with the TAS2557 device through the followinginterfaces:• USB interface– TAS2557 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 TAS2557 control• I2C interface for TAS2557 control
Features
