PAM8302AASCR

PAM8302AASCR 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, thus 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, making it ideal for portable applications. Applications include PMP/MP4, GPS, portable speakers, 2-way radios, hands-free phones/speaker phones, cellular phones.
