Overview
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.
