TI Korea (CEO Kent Jeon, www.ti.com/ww/kr ) June 28, 2012 – TI (CEO Kent Jeon) announced three analog-input Class-D stereo amplifiers for use in soundbars, aftermarket automotive solutions, portable audio docks, and LCD TVs. The TPA3116D2, TPA3118D2, and TPA3130D2 feature the industry's highest programmable switching rates and widest power supply ranges, supporting highly efficient, high-quality audio output. These devices are pin-to-pin and software compatible and support single-layer Printed Circuit Boards (PCBs). This allows designers to reuse a single layout for multiple designs, thereby reducing costs. (For more information and to order samples, please refer to www.ti.com/tpa3116d2-pr )

Key Features and Advantages of TPA3116D2, TPA3118D2, and TPA3130D2
• The industry's widest supply voltage range of 4.5V to 26V supports simultaneous operation of line power and battery power on the same board, extending battery life in soundbars and portable audio docks.
• Thermally efficient FETs support 30W x 2 operation without a heat sink requirement, or 50W x 2 operation when using a heat sink (TPA3116D2 only)
• The industry's highest programmable switching rate of 400KHz to 1.2MHz supports operation without an inductor filter and features anti-interference for clear, distortion-free audio.
• The closed-loop design provides an excellent Power Supply Rejection Ratio (PSRR) and a relatively low edge rate for waveform switching, improving Electromagnetic Interference (EMI) performance.
• Superior RDS(on) of 120µΩ at 30W x 2 operation, 20% lower than industry leaders, improves efficiency by reducing resistance during operation.

Tools and Support
Evaluation modules and SPICE models are available for $149 each for the TPA3116D2, TPA3118D2, and TPA3130D2, allowing designers to easily evaluate system-level performance and quickly amplifiers It supports integration into product design. More detailed information can be found via the link below.

Perfect signal chain for high-quality audio processing
Designers can utilize TI's PCM510x audio codec family to process digital input audio before delivering it to the TPA3116D2, TPA3118D2, and TPA3130D2. The PCM510x family features a zero-pop and click architecture that provides soft mute and analog mute capabilities, as well as out-of-band noise and jitter suppression.
