A Product Line of
ALTERNATIVE 5W STEREO AUDIO AMPLIFIER
The PAM8406 is a 5W audio amplifier with an alternative option
between Class-D and Class-AB output which makes PAM8406 very
ideally 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 wi th 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 to save the system cost and PCB area.
The efficiency of the PAM8406 is up to 90%. It can extend the battery
life, ideally for portable applications. The PAM8406 is fully protected
against faults with short circuit protection and thermal protection.
The PAM8406 is available in SOP-16L/SOP-16(EP) package.
