DIODES PAM8406DR

The PAM8406 is a 5W audio amplifier with an alternative option between Class-D and Class-AB output, which makes the device very ideal for efficiency-EMI compatible applications. The PAM8406’s low THD+N and high SNR allow it to achieve high-quality sound reproduction. The device’s fully differential output with new filter-less architecture (Class-D Mode) allows the device to drive the speaker directly, requiring no low-pass output filters and DC blocking capacitors, thus saving system cost and PCB area. The device has an efficiency of up to 90%. It can extend battery life, which is ideal for portable applications. It is fully protected against faults with short-circuit protection and thermal protection. The PAM8406 is available in the SOP-16L/SOP-16(EP) package.
