PAM8302L
2.5W FILTERLESS CLASS-D MONO AUDIO AMPLIFIER
Description
The PAM8302L is a 2.5W Class-D mono audio amplifier. Its low
THD+N offers high-quality sound reproduction.
The PAM8302L uses a filterless design that avoids the use of low-
pass filters. This new design allows the amplifier to directly drive a
speaker, making it cheap and compact. The new design allows the
amplifier to be more affordable and take less PCB area.
Pin Assignments
The PAM8302L uses less power than the Class-AB amplifiers. The
use of this product can help optimize battery life; it is ideal for portable
applications.
The PAM8302L is available in MSOP-8 and DFN3x3-8 packages.
Features
Support 2.0V to 5.5V Supply Voltage Range
2.5W Output at 10% THD with a 4Load and 5V Power Supply
Filterless, Low Quiescent Current and Low EMI
High Efficiency up to 88%
Superior Low Noise
Short Circuit Protection
Thermal Shutdown
Few External Components to Save Space and Cost
MSOP-8 and DFN3x3 Packages Available
Pb-Free Packages
