IS31AP4991A - 1.1W AUDIO POWER AMPLIFIER

Datasheet Summary

Description

The IS31AP4991A 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 1.1W of continuous RMS output power into an 8Ω load @ 5V.

Features

  • Operating from VCC = 2.7V ~ 5.5V.
  • 1.1W output power @ VCC = 5V, THD+N= 1%, f = 1kHz, with 8Ω load.
  • Ultra-low consumption in standby mode (much less than 1μA).
  • 56dB PSRR @217Hz in grounded mode.
  • Near-zero click-and-pop.
  • Ultra-low distortion (0.074%@0.5W, 1kHz).
  • SOP-8 and MSOP-8 packages.
  • RoHS & Halogen-Free Compliance.
  • TSCA Compliance.

IS31AP4991A 1.1W AUDIO POWER AMPLIFIER WITH ACTIVE-LOW SHUTDOWN MODE March 2024 GENERAL DESCRIPTION The IS31AP4991A 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 1.1W of continuous RMS output power into an 8Ω load @ 5V. An externally-controlled standby mode reduces the supply current to much less than 1μA. It also includes internal thermal shutdown protection. The unity-gain stable amplifier can be configured by external gain setting resistors. FEATURES  Operating from VCC = 2.7V ~ 5.5V  1.
