The PAM8106 offers advanced features for a range of battery- or line-powered devices including LCD TVs, wireless speakers, portable stereos, and game machines.
It operates from a wide input voltage range (4.5V to 15V) and is capable of driving both 8Ω and 4Ω speakers, which are popular in portable speaker applications.
With high efficiency, up to 92%, it is able to minimise heat generation, removing the need for a heat-sink helping to avoid the cost, weight and space associated with adding a heat-sink in the final application.
With a low quiescent current of just 15mA, the PAM8106 is well-suited for Li+ or alkaline battery-driven portable speakers, enabling longer audio enjoyment with better sound quality.
Its advanced EMI suppression, achieved through the integration of SSM technology, means that audio devices based on the PAM8106 can avoid the need for expensive filters on the audio outputs and instead use inexpensive ferrite bead filters, delivering further system cost reductions while still meeting EMC requirements.
The PAM8106 also features NCPL technology, which automatically adjusts the gain to eliminate clipping at the output signal due to high-level input signals. The PAM8106 also offers low THD+N to provide further speaker protection. Additional protection integrated into the device protects against faults caused by short circuits, and thermal shutdown, under-voltage and DC input protection is also integrated.
