IS31AP4996-GRLS2-TR ISSI

IS31AP4996 1.1W AUDIO POWER AMPLIFIER WITH ACTIVE-HIGH STANDBY MODE August 2013 GENERAL DESCRIPTION FEATURES The IS31AP4996 has been designed for demanding Operating from V = 2.7V ~ 5.5V CC audio applications such as mobile phones and permits 1.1W output power V = 5V, THD+N= 1%, CC the reduction of the number of external components. f = 1kHz, with 8 load It is capable of delivering 1.1W of continuous RMS Ultra-low consumption in standby mode (much output power into an 8 load 5V. less than 2 A) 56dB PSRR 217Hz in grounded mode An externally-controlled standby mode reduces the Near-zero click-and-pop supply current to much less than 2 A. It also includes Ultra-low distortion (0.074% 0.5W, 1kHz) internal thermal shutdown protection. SOP-8 and MSOP-8 package The unity-gain stable amplifier can be configured by external gain setting resistors.
