Stereo spatial array IC brings immersive audio experience to smartphones and tablets
April 17, 2012 // Paul Buckley
Texas Instruments Incorporated has introduced an IC that converts a smartphone or tablet computerís narrow soundstage into a much wider audio experience for consumers to offer a more immersive audio experience.
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.
The 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. The device’s easy-to-use software tool speeds development by eliminating the customer’s need for algorithm tuning and in-house DSP experts. 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.
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.
