概觀
The IS31AP2111 is a digital I2S interface audio
amplifier capable of driving a pair of 8Ω speakers at
20W when operating from a 24V supply. Due to its
Class-D output drive stage; it can operate without an
external heat-sink or fan.
The IS31AP2111 integrates advanced audio
processing capabilities, such as volume control, 20
bands speaker EQ, audio mixing, 3D surround and
Dynamic Range Control (DRC). These functions are
fully programmable via a simple I2C control interface.
Robust protection circuits are provided to protect the
IS31AP2111 from damage due to accidental or
erroneous operating conditions. Because of its digital
design, the IS31AP2111 is more tolerant to noise and
PVT (Process, Voltage, and Temperature) variation
than the analog Class-AB or Class-D audio amplifier
counterpart. It has a robust anti-pop circuit for pop free
operation during power ON. It integrates protection
features for short circuit and over temperature.
The IS31AP2111 is available in a thermally enhanced
eTSSOP-24 package.
