Description

The PAM8304 is a mono filter-less Class-D amplifier with high SNR and differential input that  helps eliminate noise. The PAM8304 supports 2.8V to 6V operation make it idea for up to  4 cells alkaline battery applications. The PAM8304 is capable of driving speaker loads as low as 3Ω speaker at 5V supply maximizing the output power.

Features like greater than 90% efficiency and small PCB area make the PAM8304 Class-D amplifier ideal for portable applications. The output uses a filter-less architecture minimizing the number of external components and PCB area whilst  providing a high performance, simple and lower cost system.

The PAM8304 features short circuit protection, thermal shutdown and under voltage lock-out.
