AudioMAX T H E TM LX1720 D A T A SWITCHING CLASS-D, STEREO POWER AMPLIFIER CONTROLLER IC I N F I N I T E P O W E R O F I N N O VA T I O N P R O D U C T I O N S H E E T DESCRIPTION The LX1720 is a highly-integrated, Switching Class-D Stereo Power Amplifier Controller IC with power and size features that make it ideal for multimedia computer applications, as well as other applications where high fidelity sound is required. With input voltage ranging from 7V15V, the LX1720 is designed to operate over the full 20Hz to 20kHz audio range. Signal distortion measurements using industry standard 1kHz signal yields THD + noise levels < 1% (10 watts output). Its high efficiency (>92%) eliminates the need for heat sinks — even while delivering more than 10WRMS across 8 ohms per channel (20WRMS stereo) with 0.1 ohm SO-8 power FETs. The LX1720's output power is limited only by external FETs and available supply voltage. While offering breakthrough performance capabilities for notebooks, the LX1720 is equally attractive for multimedia systems or to drive full-size home theatre speakers.
