PAM8406 - ALTERNATIVE 5W STEREO AUDIO AMPLIFIER

General Description

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 highquality sound reproduction.

Key Features

  • Alternative Output: Class-D or Class-AB.
  • 5W Output at 10% THD with a 2Ω Load and 5V Power Supply at Class-D Mode.
  • 3W Output at 10% THD with a 4Ω Load and 5V Power Supply.
  • Filterless, Low Quiescent Current and No EMI.
  • Low THD+N at Fully Output Range.
  • Superior Low Noise.
  • Efficiency up to 90% with Class-D Mode.
  • No Pop At Turn-on/off.
  • Fully Short Circuit Protection With Auto Recovery.
  • Thermal Shutdown.
  • Few External Components to Save the Space.

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