GENERAL DESCRIPTION
The IS31AP2110 is a high efficiency stereo Class-D audio amplifier with adjustable power limit function and dynamic temperature control. The loudspeaker driver operates from 8~26V supply voltage and analog circuit operates at 3.3V supply voltage. It can deliver 20W/CH output power into 8 loudspeaker within 0.2% THD+N and without external heat sink when playing music.
