TI Korea (CEO Kent Chon, www.ti.com/ww/kr ) November 7, 2013 – TI (CEO Kent Chon) announced the launch of a Class D stereo audio amplifier for Ultrabooks, Bluetooth speakers, tablets, and Ultrabook docking stations that delivers excellent sound despite its small size. The TPA3131D2 is the industry's first Class D audio amplifier to deliver 7W in a small QFN package. This new product provides more than three times the power output of HDA (high definition audio) audio codec devices and boasts a size that is only half that of standard discrete audio amplifiers offering equivalent output. Long battery life is also a key feature. (For more detailed product information and sample orders, please refer to http://www.ti.com/tpa3131d2-pr-kr )

Key Features and Advantages of TPA3131D2
• Powerful Sound: 7W stereo output provides more than three times the power output of the 2W HDA audio codec, enabling clear sound at high volume from Ultrabooks and Bluetooth speakers.
• Package size suitable for Ultrabooks: A 5mm x 5mm QFN package, which is only half the size of a discrete amplifier in a TSSOP package, allows for simplified board layout and achieves high output power per mm² of board area.
• Long Battery Life: Class D operation achieving up to 92% power efficiency and standby power consumption of less than 50µA provide longer battery life than discrete amplifiers in large TSSOP packages.
• Wide Power Range: Provides a low 4.5V power rail compared to 8V integrated amplifiers, supporting both AC power and 2S battery power systems with a power range reaching up to 26V.
• Complete Audio Solution: High-performance audio solutions are possible by combining the TLV320AIC3254 stereo audio codec with integrated miniDSP and the TPA6132A2 stereo headphone amplifier.

Tools and Support
The TPA3131D2EVM is sold at a recommended retail price of $149, and a PSpice model for board circuit verification is available.

In addition, you can post questions on the TI E2E™ community's audio forums and get help from fellow engineers and TI experts to solve problems.
