General Description

The IS31AP4991 has been designed for demanding audio applications such as mobile phones and permits the reduction of the number of external components.

It is capable of delivering 1.2W of continuous RMS output power into an 8Ω load @ 5V.

An externally-controlled standby mode reduces the supply current to much less than 1μA.

Key Features

  • 1.2W output power @ VCC = 5V, THD+N= 1%, f = 1kHz, with 8Ω load.
  • Ultra-low consumption in standby mode (much less than 1μA).
  • 65dB PSRR @217Hz in grounded mode.
  • Near-zero click-and-pop.
  • Ultra-low distortion (0.025%@0.5W, 1kHz).
  • SOP-8 and MSOP-8 package.
