IS31AP4990D

IS31AP4990D 1.2W AUDIO POWER AMPLIFIER WITH ACTIVE-LOW SHUTDOWN MODE December 2011 DESCRIPTION The IS31AP4990D 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 shutdown mode reduces the supply current to less than 1μA. It also includes internal thermal shutdown protection. The unity-gain stable amplifier can be configured by external gain setting resistors.
