The PAM8302A is a 2.5W Class-D mono audio amplifier. Its low THD+N feature offers high quality sound reproduction. The new filterless architecture allows the device to drive speakers directly instead of using low-pass output filters, therefore saving system cost and PCB area. With the same number of external components, the efficiency of the PAM8302A is much better than that of Class-AB cousins. It can optimize battery life thus is ideal for portable applications. The PAM8302A is available in MSOP-8, SOP-8, DFN3x3-8 and DFN2x2-8 packages.
