Preliminary Datasheet LPA2171 Filterless 6W Class- F Mono Audio Amplifier General Description Features Shutdown current:<5uA The LPA2171 is a 6W, class-F audio amplifier with a 480KHz fixed frequency switching for amplifier mode pin for switch the work mode. It offers low THD+N, 5.6W Output at 10% THD with a 2 Load and 5V allowing it to achieve high-quality Power Supply sound VDD for amplifier 4.4W Output at 1% THD with a 2 Load and 5V reproduction. The new filterless architecture allows the VDD for amplifier device to drive the speaker directly requiring no low-pass 4.0W Output at 10% THD with a 4 Load and 5.5V output filters, thus to save the system cost and PCB area. VDD for amplifier The LPA2171 is available in SOP-8. Filterless, Low Quiescent Current and Low EMI Amplifier Efficiency up to 85% Order Information Free LC filter digital modulation, direct-drive speakers LPA2171 Short Circuit Protection Thermal Shutdown F: Pb-Free Few External Components to Save the Space and Package Type cost SO: SOP-8 Pb-Free Package Marking Information Applications Device Marking Package Shipping Portable Bluetooth Speaker LPA2171SOF LPS SOP-8 3K/REEL Cellular and Smart mobile phone LPA2171 Square Speaker YWX Y: Y is year code.
