1 Description

The TAS2781EVM is designed to demonstrate the performance of TAS2781 device in a mono configuration. The design utilizes onboard controller to provide connection interface and supply voltages. TAS2781 is a mono, digital-input, Class-D audio amplifier optimized for efficiently driving high peak power into a variety of loudspeakers for various audio applications. Y-Bridge technique is implemented at the output stage of the amplifier so that is can change from two different voltage rails depending on the amount of power required at the output, improving efficiency significantly at lower power. The Class-D amplifier is capable of delivering 25 W of output power into a 4 Ω load at source voltage of 16 V. Integrated speaker voltage and current sense provides real time monitoring of speaker parameters like DC resistance and resonant frequency to protect it from mechanical / electrical damage.real time monitoring of loud speakers. TAS2781 support I²S/TDM, I²C ans SPI interfaces.

TAS2781EVM supports evaluation and development with the TAS2781 device through the following interfaces:

• USB Interface
• Software control via PurePath™ Console 3 (PPC3) GUI, USB-HID
• USB-class audio device, compatible with Microsoft®Windows® 7+
• External 100-mil headers
• PSIA – I²S/TDM interface
• I²C or SPI
• Hardware Shutdown Control
• Interrupt Output
