A Product Line of Diodes Incorporated PAM8013 3W MONO CLASS D AUDIO AMPLIFIER Description Pin Assignments The PAM8013 is a 3W mono filter-less class-D amplifier with high PSRR and differential input that eliminate noise and RF rectification. Features like 90% efficiency and small PCB area make the PAM8013 A1 A2 A3 class-D amplifier ideal for cellular handsets. The filter-less INP GND OUTP architecture requires no external output filter, fewer external components, less PCB area and lower system costs, and simplifies application design. B1 B2 B3 The PAM8013 features short circuit protection and thermal shutdown. VDD VDD GND The PAM8013 is available in U-FLGA151-9 packages.
