Through the stereo spatial array IC and companion software tool, mobile device designers can overcome the limited soundstage of closely spaced speakers by manipulating sounds in 3D space
DALLAS, USA: Texas Instruments (TI) has launched an integrated circuit (IC) that has the capability to convert a smartphone or tablet’s narrow soundstage to a wider audio experience for consumers.
Through the stereo spatial array IC and companion software tool, mobile device designers can overcome the limited soundstage of closely spaced speakers by manipulating sounds in 3D space.
The LM48903 stereo Class D spatial array is innovative spatial audio ICs designed for space-constrained applications from smartphones to ultra-slim flatscreen TVs. It features complete audio solution with 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.
It also comes with a simplified audio effect programming with an easy to use software tool. It also provides an immersive audio effect that enables differentiated products that defy physical system size to provide an expanded soundstage superior to competitive solutions.
It also two Class D speaker drivers that deliver 2 W per channel of continuous output power into a 4-Ohm load with less than 1 per cent total harmonic distortion plus noise (THD+N) to simplify system design and reduce bill of materials.
