Texas Instruments Incorporated (TI) introduced an integrated circuit (IC) that, according to the company, converts a smartphone or tablet computer’s narrow soundstage into a much wider and exciting audio experience for consumers. The LM48903 stereo Class D spatial array 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. Software tools speed 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.
