PAM8304ASR

The PAM8304 is a mono, filter- less, Class- D amplifier with high SNR (signal- to- noise ratio) and differential input that helps eliminate noise. The PAM8304 supports 2.8V to 6V operation, which makes it ideal for up to 4- cell alkaline battery applications. The PAM8304 is capable of driving speaker loads as low as 3Ω with a 5V supply, maximizing the output power. The device's over 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 in the PCB area whilst providing a high- performance, simple, and lower cost system. The PAM8304 features short- circuit protection, thermal shutdown, and undervoltage lockout. The PAM8304 is available in the U- DFN3030- 8 (Type E) and MSOP- 8 packages.
