IS31AP4991 1.2W AUDIO POWER AMPLIFIER WITH ACTIVE-LOW STANDBY MODE November 2011 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. 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.
