The PAM8106 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. Its high efficiency of up to 92% minimizes heat generation, removing the need to for heat-sink hence avoiding 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.
As a result of its advanced EMI suppression, achieved through the integration of SSM technology, 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, undervoltage and DC input protection is also integrated.
The PAM8106 is available now in a QFN5x5-32L package.
