PAM8003
FILTERLESS 2.5W CLASS-D STEREO AUDIO AMPLIFIER
Description
The PAM8003 is a 2.5W, Class-D audio amplifier. It offers low
THD+N, allowing it to achieve high-quality sound reproduction. The
new filterless architecture allows the device to drive the speaker
directly, requiring no low-pass output filters, thus saving the system
cost and PCB area.
Pin Assignments
With the same numbers of external components, the efficiency of the
PAM8003 is much better than that of class-AB cousins. It can extend
the battery life, making it ideal for portable applications.
The PAM8003 is available in SO-16 package.
Features
2.5W Output at 10% THD with a 5Ω Load and 5V Power Supply
Filterless, Low Quiescent Current and Low EMI
Low THD+N
64-Step DC Volume Control
Superior Low Noise
Short Circuit Protection
Thermal Shutdown
Few External Components to Save the Space and Cost
RoHS Pass and Green Package
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
Applications
LCD Monitors / TVs
Notebook Computers
Portable Speakers
Portable DVD Players, Game Machines
