PAM8302A 2.5W FILTERLESS CLASS-D MONO AUDIO AMPLIFIER Description Pin Assignments 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 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 thus is ideal for portable applications. The PAM8302A is available in MSOP-8, SO-8, and U-DFN3030-8 (Type E) packages. Features 2.5W Output at 10% THD with a 4 Load and 5V Power Supply Filterless, Low Quiescent Current and Low EMI High Efficiency up to 88% Superior Low Noise Short Circuit Protection Thermal Shutdown Few External Components to Save Space and Cost MSOP-8, SO-8 and U-DFN3030-8 (Type E) Packages Available Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. Green Device (Note 3) For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative.
