PAM8603M
3W FILTERLESS STEREO CLASS-D AUDIO AMPLIFIER WITH DC VOLUME CONTROL
Description
The PAM8603M is a 3W, sterero, Class-D audio amplifier with DC
volume control. It offers low THD+N, allowing it to produce high-
quality sound reproduction. The new filterless architecture allows the
device to drive the speaker directly, requiring no low-pass output
filters, which saves the system cost and PCB area.
Pin Assignments
With the same numbers of external components, the efficiency of the
PAM8603M is much better than class-AB cousins. It can extend the
battery life thus ideal for portable applications.
The PAM8603M is available in SSOP-24 and SOP-18 packages.
Features
3W Output at 10% THD with a 4Ω Load and 5V Power Supply
Filterless, Low Quiescent Current and Low EMI
Low THD+N
64-Step DC Volume Control from -75dB to +24dB
Superior Low Noise
Efficiency up to 89%
Short Circuit Protection
Thermal Shutdown
Few External Components to Save the Space and Cost
Pb-Free Package
Applications
LCD Monitors/TV Projectors
Notebook Computers
Portable Speakers
Portable DVD Players, Game Machines
Cellular Phones/Speaker Phones
