Space configurable processors

offers a surround sound experience for movies

DALLAS, Nov. 14, 2011 / PRNewswire / - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced an integrated circuit (IC) that simplifies the design and programming systems enhanced audio space for multi-speaker portable products, including laptops, tablets, bars, sounds and audio docking stations. The National LM48901 Class D quad spatial arrangement is the first in a family of innovative semiconductor solutions using distributed processing audio sound technology with large speaker to produce an immersive audio experience for applications with limited space.

• tablets, for example, have large displays offer superb high definition video, but the overall experience is hampered by its speakers with little space to produce a sound that lacks clarity and depth. They suffer from a limited recording studio, where several speakers as a single speaker, as they put together. LM48901 and companion software tool to solve this problem with the program easy to use sound effects for sound in a small surround sound experience that can be deployed in the portfolio of a manufacturer of products ranging from tablets to ring two bars and 16 speakers.
• key features and benefits

Solution

audio: IC incorporates an area of ??DSP, four Class D amplifiers, stereo analogue to digital 18-bit (CAN) (PLL ) and I2S and I2C interfaces.

Effect simplified

audio programming: easy to use software tool accelerates development by eliminating the need for a set of algorithms and internal experts DSP.

immersive audio effect: allows differentiated products that defy the size of the physical system to provide a wider sound stage than competing solutions.

• flexible multi-channel capabilities:
• Allows multiple LM48901 to be chained to support up to 16 channels of speakers and subwoofer multiple configurations.

2 W

drivers built-in speaker: Four speakers deliver D 2 W per channel output power to a load of 4 ohms with less than 1 percent total harmonic distortion plus noise (THD + N) to simplify system design and reduce the bill of materials.
