P8304 P8304 XXXYW XXXYW A Product Line of Diodes Incorporated PAM8304 3W MONO CLASS D AUDIO AMPLIFIER Description Pin Assignments The PAM8304 is a mono filter-less Class-D amplifier with high SNR DFN3X3-8L and differential input that helps eliminate noise. The PAM8304 Top View supports 2.8V to 6V operation make it idea for up to 4 cells alkaline battery applications. The PAM8304 is capable of driving speaker OUT+ 1 8 OUT- loads as low as 3 speaker with a 5V supply maximizing the output power. PVDD 2 GND 7 Features like greater than 90% efficiency and small PCB area make VDD 3 6 SD the PAM8304 Class-D amplifier ideal for portable applications. The output uses a filter-less architecture minimizing the number of IN- 4 5 IN+ external components and PCB area whilst providing a high performance, simple and lower cost system. MSOP-8L Top View The PAM8304 features short circuit protection, thermal shutdown and under voltage lock-out. OUT+ 1 OUT- 8 The PAM8304 is available in DFN3030-8L and MOP-8L packages.
