PAM8406ER Diodes Incorporated

A Product Line of Diodes Incorporated PAM8406 ALTERNATIVE 5W STEREO AUDIO AMPLIFIER Description Pin Assignments 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.
