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.
