概觀

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. IS31AP2110 provides parallel BTL (Mono) application, and it can deliver 40W into 4 loudspeaker within 0.11% THD+N. The adjustable power limit function allows user to set a voltage rail lower than half of 3.3V to limit the amount of current through the speaker. Output DC detection prevents speaker damage from long-time current stress. The dynamic temperature control is a gain control system. As chip junction temperature higher than a warning level, the gain level will decrease until junction temperature lower than the warning level. The output short circuit and over temperature protection include auto-recovery feature. The IS31AP2110 is available in a thermally enhanced eTSSOP-28 package.
