IS31AP4991A 1.1W AUDIO POWER AMPLIFIER WITH ACTIVE-LOW SHUTDOWN MODE March 2024 GENERAL .
The IS31AP4991A has been designed for demanding audio applications such as mobile phones and permits the reduction of the number of external component.

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

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 shutdo
