2.7W@5.0V MONO CLIP-LESS & FILTER-LESS CLASS-D
AUDIO POWER AMPLIFIER
Preliminary Information
May 2012
GENERAL DESCRIPTION
The IS31AP2145B is a 2.7W@5.0V mono, clip-less,
filter-less, high efficiency Class-D audio power
amplifier with automatic gain control.
The IS31AP2145B integrates AGC (Automatic Gain
Control) function to automatically prevent distortion of
the audio signal by which we can enhance audio
quality and also protect the speaker from damage at
high power levels. The AGC function and its attack
time/release time are selectable via the CTRL pin. The
IS31AP2145B also provides thermal and over current
protection functions.
In addition to these features, 90% high efficiency,
improved RF-rectification immunity, a fast start-up time
and small package size make IS31AP2145B ideal
choice for cellular handsets, PDAs and other portable
applications.
IS31AP2145B is available in a 1.5mm×1.5mm
UTQFN-9 package.
