LPA2153

Preliminary Datasheet LPA2153 Filterless 2x8W Class- F Stereo Audio Amplifier General Description The LPA2153 is a 2×8W, class-F audio amplifier with EQ function for both channel. 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. LPA2153 can display 2×8W output at 10% THD with 2 Ω load. When it provides 5V DC voltage, it can provide 2× 3.4W output at 10% THD with 4 Ω load. The efficiency of LPA2153 is much better than that of class-AB cousins with the same numbers of external components. The LPA2153 is available in ESOP-16.
