Space Array Chip Simplifies Audio Soundstage Considerations

The LM48901 configurable spatial processor promises to simplify the design and programming of spatially-enhanced audio systems for multi-speaker portable products. With companion software, the device offers easy-to-use audio-effect programming that converts a small soundstage into an immersive sound experience, deployable across an entire product portfolio. It integrates a spatial processing DSP, four Class D amplifiers, an 18-bit stereo ADC, phase-locked loop, and I2S and I2C interfaces. The LM48901’s software tool includes a speaker array coefficient generator that creates spatial audio coefficients in a few steps. Also included are Android drivers with an application note and an evaluation board with graphical user interface. The LM48901 is available in two package types: a 36-pin, 3.2-mm x 3.4-mm micro SMD and a 32-pin 5-mm x 5-mm LLP. Pricing is $2.50 each/1,000. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
