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 lowpass 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. 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.
