Texas Instruments (TI) today announced two new PurePath DigitalTM power stage devices. The TAS5261 is the industry's highest power single-chip digital amplifier power stage device capable of driving 4 ohm speakers at more than 300W, while the TAS5162 is a dual channel digital amplifier power stage device that can drive 6 ohm speakers at 200 W per channel. Drives 125 W at 8 ohms. Both devices improve the efficiency and sound quality of a wide range of audio applications, including those previously unable to use digital amplifiers due to power limitations, such as high-end DVD receivers and mid- to high-end audio/video receivers (AVRs).Forward Concepts released a report titled "Audio Chip Market: Multimedia Foundation" in June 2006. The company's president, Will Strauss, pointed out: "Digital amplifiers and Class D chips are promising components in the audio market, with compound annual growth rates expected. Up to 40%. As the world leader in Class D and digital audio amplifier technology, TI's new TAS5261 delivers up to 17A of drive current in a smaller silicon footprint, setting a new benchmark for amplifier performance in this market."
For 300 W systems (4 ohms) used in AVR, etc., in the past, only the less efficient Class AB amplifiers or modules were used due to the power and current limitations of the digital audio power stage. Now, with the TAS5162 and TAS5261 single-chip power-level devices, designers will be able to take advantage of TI's industry-leading Class D technology to achieve greater than 95% efficiency and 110 dB signal-to-noise ratio (SNR). The total harmonic distortion and noise (THD+N) of the TAS5261 at 125W power (8 ohms) is less than 0.09%. The TAS5162 can drive two channels simultaneously at 200W. Both make the system consume less power and less heat, while improving performance and sound quality.
In addition, unlike other high-power digital amplifiers or Class-D solutions, this single-chip device eliminates the need for discrete components such as MOSFET H-bridges, reducing board space, simplifying layout and heat sink design, and reducing manufacturing costs.
Art George, senior vice president of TI's High Performance Analog Business Unit, states: "TI Class D amplifier expertise enables OEMs to take full advantage of all the benefits of digital amplifiers, including low-cost, fully digital end-to-end solutions and ultra-clear audio Even at the highest power, it does not cause signal attenuation. The TAS5261 can reliably drive more than twice the power and current of existing digital amplifier power levels, and its performance is unparalleled."
The TAS5162 power stage is also pin-for-pin compatible with current TAS51x2 devices, allowing OEMs to drive 100 W (TAS5142), 125 W (TAS5152) or 200 W (TAS5162) per channel with a single board design. This saves multiple design costs and simplifies the process. The two new power stage devices also feature enhanced gate drive technology as well as the TAS5152 and TAS5142, as well as periodic two-stage overcurrent and undervoltage detection.
The TAS5162 and TAS5261 digital amplifier power stage devices are based on TI's PurePath Digital digital technology, enabling consumer electronics manufacturers to deliver all-digital end-to-end audio products for advanced playback and true-to-life design in a compact design The sound quality. PurePath Digital delivers true soundtracks or music in a way that artists can expect, bringing the best of high-end digital entertainment to the average consumer. Other digital and high-performance analog products that support audio applications, such as DSP, switch-mode power management, analog Class-D amplifiers, and audio converters, are also complemented by PurePath Digital technology.
The TAS5261 300 W digital amplifier power stage is available now in volume quantities and is available for order. The device is available in a PSOP-3 package and is priced at $5.25 each in 1,000-unit quantities. The TAS5162 200 W stereo digital amplifier power stage is available in PSOP-3 and HTSSOP packages and is expected to be in volume production in December.
