Preliminary Datasheet LPA2154 Filterless 2x8W Class- F Stereo Audio Amplifier General Description The LPA2154 is a 2×8W, class-F audio amplifier with a mode pin for switch the work mode. 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. The LPA2154 is available in ESOP-16. Order Information LPA2154 □ □ □ F: Pb-Free Package Type SP: ESOP-16 Features  500KHz fixed frequency switching for amplifier  2×3.3W Output at 10% THD with a 4Ω Load and 5V PVDD for amplifier  2×4.8W Output at 10% THD with a 4Ω Load and 6.0V PVDD for amplifier  2×8W Output at 10% THD with a 2Ω Load and 6.
