LPA2101A
Filterless 30W Class F Mono Audio Amplifier With AGC function
概述
The LPA2010 is a 3W, class-D audio amplifier. 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 LPA2010 is available in MSOP-8.
