LPA2164 Overview
The LPA2164 is a 8W, class-F audio amplifier with boost convertor integrated. It offers low THD+N, allowing it to achieve high-quality Power Supply sound reproduction. The new filterless architecture allows the device to drive the speaker directly requiring no low-pass output filters, thus to save the system cost and PCB area.
