2.5W FILTERLESS CLASS-D MONO AUDIO AMPLIFIER
Description
The PAM8302A is a 2.5W Class-D mono audio amplifier. Its low
THD+N feature offers high quality sound reproduction. The new
filterless architecture allows the device to drive speakers directly
instead of using low-pass output filters, therefore saving system cost
and PCB area.
With the same number of external components, the efficiency of the
PAM8302A is much better than that of Class-AB cousins. It can
optimize battery life thus is ideal for portable applications.
The PAM8302A is available in MSOP-8, SOP-8, DFN3x3-8 and
DFN2x2-8 packages.
Features
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, SOP-8, DFN3x3-8 and DFN2x2-8 Packages Available
