Stereo Spatial Array IC brings immersive audio to smartphones.

Press Release Summary:

Housed in 2.7 x 3.2 mm micro SMD package, Model LM48903 and companion software helps mobile device designers overcome limited soundstage of closely spaced speakers by manipulating sounds in 3D space to create immersive cinematic experience. IC integrates spatial processing DSP, 2 Class D amplifiers, 18-bit stereo ADC, phase-locked loop, and I2S/I2C interfaces. Speaker drivers deliver 2 W/channel of continuous output power into 4 W load with less than 1% THD+N.

TI Stereo Spatial Array IC Brings Immersive Audio Experience to Smartphones and Tablets

Configurable spatial processor creates mobile cinematic experience

DALLAS, -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced an integrated circuit (IC) that converts a smartphone or tablet computer's narrow soundstage into a much wider and exciting audio experience for consumers. The stereo spatial array IC and companion software tool enable mobile device designers to overcome the limited soundstage of closely spaced speakers by manipulating sounds in 3D space to create a bigger, more immersive cinematic experience. The LM48903 stereo Class D spatial array joins a family of innovative spatial audio ICs designed for space-constrained applications from smartphones to ultra-slim flatscreen TVs.

Key features and benefits

-- Complete audio solution: IC integrates a spatial processing DSP, two Class D amplifiers, 18-bit stereo analog-to-digital converter (ADC), phase-locked loop (PLL), and I2S and I2C interfaces.

-- Simplified audio effect programming: Easy-to-use software tool speeds development by eliminating the customer's need for algorithm tuning and in-house DSP experts.

-- Immersive audio effect: Enables differentiated products that defy physical system size to provide an expanded soundstage superior to competitive solutions.

-- Integrated 2-W speaker drivers: Two Class D speaker drivers deliver 2 W per channel of continuous output power into a 4-Ohm load with less than 1-percent total harmonic distortion plus noise (THD+N) to simplify system design and reduce bill of materials.

Tools and support

The LM48903's web-based Speaker Array Designer tool includes an easy-to-use coefficient generator that creates unique spatial audio coefficients in a few easy steps. Also included are Android drivers and an evaluation board with graphical user interface.

Availability, packaging and pricing

The LM48903 is available today in a 30-bump, 2.7-mm x 3.2-mm micro SMD package. Suggested retail pricing is $1.75 in 1,000-unit quantities.
