21ic Texas Instruments (TI) introduces an integrated circuit (IC) that simplifies the design and programming of audio systems for multi-speaker portable product space enhancements, including laptops, tablets, sound bars and audio docking stations . National's LM48901 Space Array is the first innovative audio IC family (including four Class D amplifiers) with distributed sound processing and speaker array technology, which brings a presence for space-constrained applications. Audio experience. This article refers to the address: http:// For example, some tablets' widescreen screens can provide impressive high-definition video, but because the user's overall experience is hindered by the audio generated by tightly spaced speakers, lack of clarity and depth, Produces the effect of tightly spaced speakers of audio. Since multiple speakers are brought together, the user sounds like there is only one speaker, which limits the sound field. The LM48901 and accompanying software tools solve this problem with easy-to-use sound programming that converts a small sound field into an immersive sound experience that manufacturers can use across the entire product portfolio, from tablets to 2 A sound bar with 16 speakers. Main features and advantages Complete audio solution: The IC integrates a spatial processing DSP, four Class D amplifiers, an 18-bit stereo analog-to-digital converter (ADC), a phase-locked loop (PLL), and I2S and I2C interfaces. Simplified sound programming: Easy-to-use software tools speed up development without the need for algorithm adjustments and internal DSP experts. Integrated 2 W speaker driver: 4 Class D amplifiers can output 2 W continuous output power per channel to 4 ohm load, less than 1% total harmonic distortion plus noise (THD+N) to simplify system design and reduce bill of materials . The LM48901's software networking tools include an easy-to-use speaker array coefficient generator that creates unique spatial audio coefficients in a few simple steps. Also included are Android drivers and application annotations, evaluation boards, and graphical user interfaces. Availability, packaging and price The LM48901 is available in two package types: a 36-pin 3.2mm x 3.4mm micro SMD and a 32-pin 5mm x 5mm LLP. 1000 suggested retail price is $2.50 Cixi Zhongyi Electronics Factory , https://www.zybreadboard.com
Immersive sound: No matter the size of the physical system, it can provide an extended sound field that is superior to competitive solutions to achieve differentiated products.
Flexible multi-channel capability: Multiple LM48901s with daisy-chain support up to 16-channel speakers and multiple subwoofer configurations.
