Texas Instruments announced the LM48903 stereo Class D spatial array. The LM48903 is 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 TI LM48903 is available now 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.
The TI LM48903 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 is ideal for space-constrained applications from smartphones to ultra-slim flat screen TVs.
The LM48903 is a stereo Class D amplifier that utilizes TI’s proprietary spatial sound processor to create an enhanced sound stage for portable multimedia devices. The Class D output stages feature National’s edge rate control (ERC) PWM architecture that significantly reduces RF emissions while preserving audio quality and efficiency.
