The PAM8406 is a 5W audio amplifier with an alternative option between Clas s-D and Class-AB output which makes PAM8406 very ideal for the applications.
Efficiency - EMI compatible. PAM8406 offers low THD+N, high SNR allowing it to achieve high-quality sound reproduction. The fully differential output with new filter less architec ture (Class D mode) allows the device to drive the speaker directly, requiring no low-pass output filters and DC blocking capacitors, thus to save the system cost and PCB area.
The efficiency of the PAM8406 is up to 90%. It can extend the battery life, ideal for portable applications. The PAM 8406 is fully protected against faults with short circuit protection and thermal protection.
